Struggling to Keep a Full-Time Job

I hate that I can’t hold a full time job without wanting to kill myself. So, I hold a part time job. And I suffer financially because of it. If I worked full time, I’d have so much more money. I wouldn’t even have to think about it as much. I wouldn’t even really spend it, I’d just hold onto it for emergencies. I have to accept that maybe I really am…behind in life. I’m not actually anywhere above anyone. I haven’t ‘been through more’ and I haven’t ‘worked my way up’. I’m just trying to have peace with myself. I don’t believe money makes people better, successful or happy. I believe money is for stability. I guess I’m stable. So I don’t even know why I’m so bothered by this. I think it’s because taxes are coming up soon and I have to shell out a ton of money to make up for my untaxed tips. I need a new phone and honestly I’ll need to prepare for future car payments. Can I hold another job? I don’t think I can do it.
