Life is exhausting

I just turned 26. Never been in a relationship, never had a real job. I have depression and anxiety, and ADHD. I can't motivate myself to apply for a real job even after finishing my degree, I'm about to lose my second internship, my life is just very lonely and I can't make any friends. I can't get out of bed in the morning, I'm constantly tired, I'm constantly worried about everything. My biggest accomplishment is getting my driver's license when I was 21, and I don't even drive. I want to travel, I want to love, I want to be happy. But I can't. I don't know what to do, I just constantly cry because nothing is working out.
