Cant sleep in a middle of a mid life crisis.

Hi everyone. Ill turn 21 next month. Still yet not in university. I mean i joined once ani dropped. Currently im in process of rejoining university and all. But still i dont work. And kind of in midst of everything and this has made me feel like the biggest loser out there. Cant sleep, eat, drink or anything. Its almost 5 ani here i am venting to people who probably wouldnt care much. I dont really have any close friends to vent about im just a floater friend. And ive been single for a year and half so dont really have a boyfriend either. Sometimes its just too much to keep everything bottled up inside wjen you have nobody to vent to. Also im thibking about going for a morning coffee maybe alone maybe some company. Idk. Any advices?
