I feel lost

I’m quite young, and for the most part have a pretty boring life, I feel like I’m doing nothing right I’ve had the same “friend group” for roughly 10 years now and I haven’t really talked to many people outside of them, I watch as all of them live their life while I’m sat here doing nish, I know this is probably my fault, but everytime I do try make an effort something bad always happens and I don’t know what to do anymore, first and only job, fired within 3 months, try to talk to a girl, watch her walk away with another guy when I was the one invited. I also have no clue what I’m gonna do in the future I’ve always been smart I know im capable but i have no idea where to start and what to do, everyday feels like It’s coming to a grand finale or a videogame ending of sorts and I find myself spiralling deeper and deeper while also having this weird feeling of something inbetween stress and anxiety but no clue of where it comes from. I’m nearing the end of school and wish to study abroad but that is pretty much all I’m trying to achieve at the moment and I have no idea if im on track or not and sometimes I feel like just disappearing.
