<human>: Can you condense the text into three sentences or less?

So I'm kinda depressed, I've been to r/depression and r/SuicideWatch, and I'm not gonna kill myself any time soon, I think it would be foolish and wasteful to throw away almost all of my life for how my high school experience is going so that's why I'm not posting there for help.

I'm here to ask the social people of reddit, how do I actually talk to people? I've put myself in a position (almost completely my fault) where I have spent the last 4 years of my life slowly becoming quiet and shy, and rarely talking to anyone in my school. I've gotten to the point where Ive made about 5 good friends (woohoo) but I cannot seem to talk to anyone who I'm not directly introduced to, since I've (technically) been in the same classes with them for 4 years, and just never spoke to them. I know who everyone in my class is, and I'm pretty sure they know me back, I just kinda sit silently an don't talk to anyone. I think it would be extremely awkward to just start talking to some dude who's sat near me for years as if we're two strangers meeting for the first time.

So yeah, I'd rather not become a lifeless vegetable before college, and I would like to actually have some form of social interaction with others.
<bot>: I can't talk to other people, I'm totally and unnervingly socially awkward. I'm kinda upset about it, any tips?
