How do I go on??

I work 45 hours a week making $13 an hour . My checks are like $770 every 2 weeks and after I pay my car payment, insurance, dental, rent, WiFi, and groceries , im left with $6.00 in my account until next pay day. I’m only 19 and just graduated highschool in May. I didn’t go to college because I can’t afford it and my parents aren’t in my life as I’m sure you could tell because I pay my own EVERYTHING and I just feel so down. I’m getting depressed. I’m blessed because I have just enough money to survive the necessities but I haven’t bought makeup in over 4 months, haven’t had my hair, nails, or brows done in years. I just want to be able to take care of myself physically and mentally but I feel so depressed. I can’t go anywhere or do anything because then you gotta get gas or pay for food or whatever else. I haven’t spoken to a friend since I graduated because I don’t want them coming to my empty apartment or for them to ask me to go out. I could get a second job but I’m a shift lead at my job which honestly mean in my industry I’m doing just as much work from home as I am at work . How do y’all survive? How do y’all stay positive? How do you keep going when all you see is darkness? Why do I have to keep struggling I’ve never felt stable in my life and now I’m not even 20 thinking about horrible things just to get make ends meet. No joke... should I do porn? Or sell feet pictures? Or something idk what to do anymore. I literally want to die.
