Prior to college I basically had no friends in school for about 4 years, due to a mix of anxiety and feeling like I didn't need them. I was a mute in class and avoided every type of social interaction. The usual things applied: absolutely terrified of group assignments, having anxiety attacks prior to presentations, dying inside when entering rooms when everyone's already seated, etc.
I got into a depression (that's still lasting) and had some bad moments yet I didn't (don't) want to see a therapist or let my mother know about any of this.
It had been tough but I managed to get a diploma in the end and get into college.
During the holidays prior to college I found out about this community and figured that college is a great opportunity to face my anxiety issues and to finally make some friends and talk more, since it's a fresh start.
So I did. Anxiety was very present but I forced myself to let my voice be heard during group assignments and talk to people next to me about their interests. I formed a group with two friends I made and we do practically everything together in college - sitting in class, doing assignments, eating, leaving, etc.
Atm we only talk when in college which makes it a bit hard to see them as 'real' friends but that might change with time.
It's probably not that huge of a thing for others but considering I haven't had any people to hang out with in school for many years it feels like a big improvement.
Unfortunately I do still have a bunch of other anxiety issues but at least this gave me a bit more of a positive mindset.
