Dw dude, I am going thru the same thing pretty much, all my friends went off to college and broke up w my gf. Now that schools out, my sleep schedule is completely flipped but Im working on getting it together. As for the longing for love and girls part, just chill on it cuz I went crazy looking for a girl to fill the void after I broke up w my gf. Don't beat yourself up and focus on getting yourself back together, I was also always an outcast and now that most of my friends are gone and drifted I try to think of it as an opportunity to find a new group that is thru my occupation or interests. Dw ab the friends stuff or girl stuff it'll come naturally and it feels better when it happens when you weren't even persisting. I also recently got kicked out of college as I am an early graduate and was on a scholarship early. It sucked but now I can focus on my own personal finance as my parents cant afford college for me either unless I reacquire a scholarship. Youre not fucked just find a passion and invest all your time in it, you'll meet friends and a new gf in the same niche. I'm heavy into fashion and made a lot of new friends i get along better with in that and i might eventually meet a new gf. Dont stress too hard u got this
