I feel worthless

I’m not trying to sound dramatic or anything lol. Don’t take this the wrong way, I am not suicidal or anything. I am 21 years old. I’ve dropped out of college, I live with my parents still and I suck at my waitressing job. I feel like my boyfriend doesn’t like me as much now but I can’t leave him because i don’t know what I would do without him. I am so lost in my life
