i would suggest that you next step should be to further develop yourself so as your confidence will not be deminished by other peoples moods.
as for the fun and interactons, you have alot of control of the amout of interactions you have(through the amount of interactions you start) and if you can interact in a way that people open up and you find cominalities these reactions will be fun.
this type of senario you are entering is a good test for yourself of how you have developed, meeting people who new the old you will be intimidating but this can highlight areas of your game to you that you need to concentrate on. you are entering a stressful situation but being able to handle a situation like this and feel comfortable is your next step.
