you're pretty much describing my life story here. its all been very similar for me too. anxious as hell most of my life, was also a mute at school, they had to call my mum in to talk about me because they were so worried. at home around the people i know i was loud but as soon as i was outside or a stranger came to the door, i crawled back into my shell again. never had friends in primary school, had one or two girls who sympathised with me enough to look out for me during high school but i never met them outside of school and was honest why, that i had problems going out. thankfully they understood but after school was over we only kept in contact via text before that eventually fizzled out too.
college was absolute hell. i didn't even want to go but my dad is strict so he said either college or get a job, because i couldn't find a job (being 16 and most places told me the requirement was 18) i had to go to college where i went back to being a complete mute again and as a result i was bullied horrifically. name calling on a daily basis, laughed at, had things thrown at me, openly embarrassed many times. even my teachers seemed to hate me. i was treated like a freak, no one wanted to be anywhere near me. and like your average mousy type i just took it. i never responded or reacted, i just let them do it and went home and prayed for death. but out of a college full of thousands of hateful people there was of course that one saintly person who took pity on me, for me it was a careers adviser who was so lovely that i opened up to her and told her that i hated it at that college and that everyone was mean to me and so she advised me to go to a different college and helped me do all the work to send me there. which in itself was a challenge due to my anxiety. a catch-22, on one hand i wanted to leave cos i hated the college that i was at but on the other hand i was too scared to move to another college and start again.
but eventually i went for the latter and it was the best decision i made because in comparison the second college was a God-send. everyone treated me better but thats also because i forced myself to open up a little bit more. i spoke more, dressed more confidently, even walked confidently. but i didn't do a whole 180 because i still had anxieties. i finally made one friend... but often struggled to go out with her.
oh and presentations were a nightmare, in college they always want you doing a presentation once every few weeks and i always tried staying off on those days or getting out of it. boy i lied so much about 'doctors appointments' etc to get out of class early to avoid doing a presentation. but sometimes i did have to do one and it would make me feel nervous for days/weeks leading up to it.
overall i did still enjoy my experience there. and then went to uni and loved it there too but again my social life was non-existent. friendships only went as far as inside uni, if they invited me to a party i would never go and always used the excuse that i was 'working that day'. same scenario with presentations, i missed one and it almost jeopardised my mark
there was a guy that liked me at uni too but it was never perused because of my nervousness. i liked him too but he was overly confident thats why i avoided him, i didn't think i'd be good enough for him being the complete opposite. so whenever he used to smile at me i turned my head the other way and pretended that i didn't see him.
and i even went as far as changing one of my courses early on, one that i really wanted to do but due to the lamest thing that happened because of my anxiety i had no other choice
basically when i first started there was this class i really wanted to take but i stupidly arrived at the lesson a few minutes later, looked through the window and noticed that the class was full and everyone had already taken their seats. a normal person would have just walked in and found a seat, me - i stood outside the door and went through a 10 minute battle mentally screaming at myself to just open the damn door and walk through... but sadly i couldn't and i let the anxiety win. so i turned around and went home then send an email to my tutor asking her if she could send me to a different class. thats how bad it was. anxiety man... its so crippling. my entire life has been ruined by it. Gosh I wish i was normal, I'd probably be living a much better, more fun right now than what I'm living now. I know for certain I'm an extrovert but I'm stuck inside my introvert body, screaming to get out
