Hi. I'm 25 and work as a Shift Lead for a large retail pharmacy. I've been with the company 3 years, and I have done every position on the store level including pharmacy technician though, I never got certified. I kept asking for new positions because I would rapidly go from loving my job to hating every moment of it. We have a 8 call out limit per a year and I've got to 7 each year. Lol. I'm already on 5 this year. I need help. I hate everything about being in a leadership position so much. I hate making decisions, but mostly hate working with customers. I've been getting angry just that the customers exist. When I'm home all I do is dread my next shift. I'm extremely depressed, and constantly on the verge of balling my damn eyes out. 
I just feel like there is nothing else I can do. I have no skills. I'm in school for database administration, but I still have a year and a half before I finish. My depression was so bad last " session" (online school) that I failed one class and got a 70 in the other. I have never had a grade below a 80 :(.
All I've ever done is retail, and I'm clearly not in a spot to continue in it. I have an appointment with my first therapist in June, but I don't know if I can wait that long to possibly get help. 
My boyfriend is super upset because he doesn't make enough to cover our bills alone.
I did ask my boss about stepping down, but he told me there's no room. I just want to die honestly, but too big of a wuss to do anything about it. 
I would love any input anyone could offer. Thank you for reading.
