Hey bro just be careful 8 years ago I tried to "read people" by studying, reading books on body language, taking classes in college on psychology, sociology, etc. And what I learned or got out of of I becoming skeptical on everything and on everybody. I've seen people take psychology n body language courses and become weird people bcuz you are constantly judging and sizing up people which is bad if you are very reactive. My suggestion is its o.k. to see the clues, the tells but never over react. Just let things be n have fun with the learning process. If she rolls her eyes up....so what. If she crosses her arms so what. If you ask her a question and she looks down so what. Theses courses will drive you insane if you start to read them too deep.
If body language isn't helping you, then you're using the tool wrong, honestly everything you explained sounds like you have a lot of inner game issues. If you're always expecting the worst, that is your mentality not the tools, or the knowledge. Your mindset of oh my god she crossed her arms isn't conducive to the proper behaviors that attract women, they'll fuck your game up massively if you're not just reading her body language and using it to maneuver through the courtship process and understanding when and what to do.
Body language isn't about sizing anyone up, or judging them, it's about understanding them. It's about being observant, and understanding, while related not at all the same.
Well, you should never ever go too crazy about any signal. Body language is a process that requires you pay attention to environment, idiosyncratic behaviors, base lining, clusters, etc.
Body language is all about understanding their emotional state not judging it, it's not about you saying "oh my god, she crossed her arms I'm fucked, what am I going to do to open her up?" Crossed arms can mean she is cold, uncomfortable, an idiosyncratic behavior, etc. There is no one sign that means one thing.
Part of the courtship process in general and about attractive behavior is YOUR behavior not just HER behavior. Body language is a form of communication and communication isn't you just observing her behavior, you must be aware of your behavior too, including over reacting to a girl looking down. Note: a look down is a sign of submission that is connected to attraction often, it's recorded in anthroplogist, zoologists, and psychologists studies of the courtship process. So a look down is GREAT thing, I'm not sure why you'd be paranoid about a girl looking down if you were actually well studied in body language. Check out the video below.

How much did you study body language? Everything you just said showed more improperly applied knowledge than to understand it and use it as a tool.
Peace and Love,
Just another guy from back in the day.
