Would really appreciate any advice anyone has.. feel like i've hit rock bottom..?

i did the same thing in highschool. i focused so much on making friends and people not liking me that i started to not be myself around people with out noticing it. other people will though but they won't be able to pinpoint it exactly but they just won't like you. they'll just feel something off about you. just stop thinking about it so much and when you meet people be yourself. it seems like you can't let loose either in fear of them not liking you. i still do that. i catch myself being all serious and technical because i don't want to seem weird or overly excited. i catch myself and just relax and laugh a little. say what's on your mind.. not what you think you should say to start conversation. and maybe the people you can't talk to aren't your type of people. you'll know when it's effortless to find a topic. but you can't get along with everyone and not everyone will like you. but it gets hard to remember that when youre discouraged. gone luck!
