For some reason, I'm also feeling so depressed, sorry to rant

Idky but I feel like despite having friends who are lovely at my college, I don't feel as though they're really close ones (I get very anxious in social interactions at times) and since I'm gonna be leaving full time education and turning 18 very soon, I just feel very... down and alone. :(

I wanna go into the music industry but that's extremely competitive and idk what's gonna become of me. 😭

Sorry to rant about another crappy problem on this sub, but is it common to feel like this?
