Feeling alone and depressed

My life has been an emotional rollercoaster. I'm ready to just say "fuck it" and give up on trying to be happy. I have no one I can express my feelings to who will actually listen. No real friends (ones that text me back anyway) and my mom will hear me out but won't listen and doesn't even try to offer advice or make me feel better. I'm in a slump right now and just feel so alone and having no body to talk to is making me feel even worse. I'm embarrassed by the lack of friends I have and also super jealous when I see people I graduated with post all over social media. It's really getting to me.

My boyfriend and I are not meant to be together. Constantly arguing and I'm always sad because of it but because he's literally the only person outside of my family I have, I don't want to let him go. He's legit my only "friend".
