I’m lost

I feel so lost. I don’t know who I am, what I want what makes me happy, I’ve got nothing. I’m working a new job that I felt obligated to get by myself but I hate it and it honestly makes me feel really bad. The hours are horrible, I can’t go see my family and I can’t go to the gym consistently because my hours are all over the place. I really just want to be happy and I feel everyday I just dislike my life more and more even though I already disliked it. I’m stressed cause I’m unhappy and then I get even more stressed cause my job makes me miserable. I even started getting a stress rash on my collar bone. I just feel so alone and helpless. I’m in my prime years but I don’t have friends, I try to make friends at work but no ones ever interested. Im not fulfilling my full potential and it sucks. I have an associates and I can’t get a job in my field because I’ve never worked before and my fear makes me not want to take the chance to even apply. Fear is taking over me, I don’t take chances cause I’m scared of being rejected. I’m just always looking down and feel like I’m in a never ending black hole. I’m so tired of being tired, miserable, sad, alone and the list goes on. I wish it was only temporary but I’ve been feeling like this since I was 16, I’m now 20. I’m going to turn 21 in a few weeks and I’m dreading it cause I have no friends to celebrate it. I’m just gonna be stuck at work hating every hour. I just need some help.
