Damn right.

You guys have left me with some amazing advice. I've now realised what I need to do.

1) Don't let their jokes etc bother me in the slightest way, even if they really do. Always laugh it off.
2) Get over my nervous habits of when I am in a social group situation, always be able to speak out and have the confidence to be completely myself. When I am eventually comfortable enough to be myself around people, I am extremely witty, funny and generally charming. Usually what happens with girls is I get slightly friend zoned, then when my true personally shines they are instantly attracted to me. I need to be like this ALL the time. So if someone says a joke to me, the normal me can instantly think of a comeback but the nervous me in a group scenario, my brain almost freezes and I have nothing to say. This is probably going to be really difficult but I know I can do it with some practice.
3) Be more confident, If I can increase my confidence I can really portray it in every thing I do. Body language etc. I've started to work out again, and I remember last year when I did work out I generally felt better about myself.
4) If all goes to shit, start fresh with some new/old friends I haven't seen in a while.

I will try and update you on how it goes, thanks a again!

It's tough, i have been there and from experience, focus on cultivating your inner strength, not taking shit attitude, this doesn't mean you are going to beat every man down who starts taking the piss out of you, but let it roll over you, take the piss back and be harsh with it, start developing the attitude of being a top dog, as much as we like to pretend that we are all civilised, ultimately we have an animal nature, and that is about subverting those who come across as weak, in this case those who come across as weak in a social environment.

Start developing this attitude, but sometimes the biggest step in developing this attitude, is saying goodbye to lousy mates, always be careful who is in your environment, develop an attitude of abundance. I have disposed of so many so called friends over the years, because their attitude was destroying my drive for getting pleasure out of life.
This is not going to be easy, but once you realise that you are not a lowly worm scraping on the dirt of the ground, but a man who has his own right in everything you want, people will treat you differently.

Unfortunately for myself the only time when i let this slip is with women if i go through a dry spell, hence why i am on this forum, looking for self improvement tips on this field , but that is something i have to develop upon myself, generally speaking i went through this a few years back and i don't look back. It may sound cliche and generic, but i can't emphasise more on taking up a martial arts, everyone has their thing, but for me that really changed how i acted in every way, posture, speech, in general people are receptive and pick up on these inner changes.

An alpha male is a leader in how he thinks, perceives and interacts with others.

He is not afraid to speak his mind. He takes charge when required. He has a confident stride and gait. And he never settles for disrespect from anybody.

You will never be an alpha if you let the opinions of others take toll on you.

Have confidence in yourself. Know that you aren't a bitch. When someone throws you a curve ball, throw it right back, while smiling and carrying on as if they did not interrupt you one bit.

Alpha's know they are the shit. If anyone thinks differently, who cares?

I think I've found a solution for all this. Recently I've started to meditate. I find that it really soothes my brain, before it was like watching 10 televisions all playing the same thoughts simultaneously, and now I can just jump back to 'nothingness' and a completely clear vision. What this does for me is it allows me to have much steadier eye contact, When I look at my friends and stare at them their eyes trembles and they look away. My comeback's are far better because of this too, as I am thinking clearly. This has honestly helped me in so many ways. Its helped me understand better at college, I can talk to girls even better than I already did, and I am all round a more 'intresting' guy that people would want to be around. I think this will really help me, I have now a more 'don't give a fuck' attitude and I speak completely freely. Shit doesn't faze me anymore, someone could come up to me and say to my face 'You smell like my shit' and I would completely stare at them in the face, where as before I would be like 'WHAT THE FUCK'. I don't get fazed at all when I am in this meditated state. Its awesome!

And the other problem I had was taking shit too seriously, jokes etc. What I've trained myself to do is if someone does say a joke I just completely ignore it and laugh it off, or I acknowledge the joke and make another joke on top of it. Recently I've noticed I have a lot more respect around everyone, and when I speak I talk extremely calmly (again helps from meditating). I talk with a steady voice, steady eye contact to everyone. At this age I don't know anyone else who does this like I do. People are instantly interested in what I have to say as it looks like I am saying it with tonnes of confidence. I can now speak and everyone listens to my ideas, my friends have said to me 'you seem different today man' etc so I know I am doing something right.

Tip that works for me: How I go by taking a joke, that used to offend me, is inside my head I think of the Eric Cartman voice from southpark. And I think 'You guys are being soo mean' or 'screww youu guyss' (like in his trembling crying voice ) and this automatically makes me laugh, and this time round its actually a real laugh and over time people have really stopped taking the piss.

I am really all over self improvement. My goal, for myself, is to be able to be charismatic, charming at all times. If I can master this shit before I leave college, I will get so much pussy. (College here in the UK is basically the last two years of highschool before going to uni btw) This is because I am surrounded by little boys, and all the girls want a real man. The way my friends pull and get laid is literally being crude to them, picking them up and throwing them about (literally, physical contact) or obviously hitting on them at a party. They have no game what so ever. This is honestly a once in a life time opportunity and I am going to have so much fun with it
