So, this might be a long rant, but here's the deal, As a kid I was really open, friendly, outgoing, all that good stuff, and although I was never remotely even a jock or anything like that, I was pretty popular at school, my teachers liked me and I had a ton of friends.
The older I grew however, the worst it got, I went to an all boys school, kindergarten all the way through high school, and ny the time I hit high school and we had to go to classes with girls from other schools and me and my friends basically discovered girls, I found that I become extremely tongue tied and shy around them, even though I'm very talkative around my friends and family, but the moment a girl I don't know enters the room, I turn into Raj from Big Bang Theory, it's usually better if I had some friends around me, then they kinda give me safety but if I'm at a new environment, I rarely spoke.
Fast forward to college and things became even worse since I went to a new college where none of my lifelong school friends went, I made a couple of friends there, but nothing really serious, and my problem with women persisted, I eventually became able to "pretend" to be at ease and relaxed, which enabled me to have normal conversations and even make a few female friends there, but I would only be able to put up the act for like an hour max before I clam back up again, also I'm kinda tall and big and according to people I have this permenant upset/angry look on my face (even though I never really get angry, I'm not that kind of person) which causes a lot of people to walk up to me and go "are you ok ?"
I also developed this habit where I dwell for too long on my mistakes no matter how minute or unnoticed they are and I would usually get this feeling whenever I'm somewhere and there's a group of people nearby laughing or whispering that they're laughing at me for some reason.
Flash forward to after college (I'm 25 right now) the social stuff have gotten better thanks to me having a job where I'm forced to interact with a lot of people, I still get extremely tongue tied around women though, like the last time I said hello to this woman I liked I swear my mouth moved but no sound came out and I developed full blown health anxiety due to a relatively log period of (non life threatening) illness and sudden deaths in my extended family. Also I found out that there is a history of cancer on both sides of my family as well as a history of depression and anti-depressant abuse as well as dementia on my mom's side, so...yay me.
Anyways, so now I'm living life with two personas, one of a (somewhat) funny, talkative friendly goof, which is closer to my true persona and is how my close friends and family know me. And one of a quiet, extremely polite but awkward dude who knows a lot of trivia info and always looks upset for some reason, which is how most other people view me.
I'm also under a lot of stress from work, where we're building up this new business where we invested the grand majority of our money, and I no longer see any of my friends because of conflicting schedules or them moving away for work...etc. So my day is basically get up, go to work, get to the gym and then go home and Netflix till bedtime, this loneliness and the fact that I feel like I'm getting older and still don't have a GF at a time where most of my friends are engaged, married or in serious relationships (heck one of them already got married, had a kid and got divorced already lol) leaves me feeling lonely and crappy as hell.
I don't know if this is anxiety or something worse. (Long rant)
