I don’t know why I’m not happy

I have a job. I’m in school (Kinda. Some semesters I don’t take classes). I have a few friends that I care about. Yet I feel very alone. I hate myself. And I feel like the void that I felt like in my worst time in my life. I can’t tell anyone about it, simply because I have nobody to tell. I wouldn’t want to put the weight on any of my friends, and I’m not in therapy. I feel like I’m just being dramatic, but I can’t force myself to feel any other way. Anybody else feel like that sometimes?
