Struggling with life and need someone to hear me out

Salam, I've been feeling so low lately, like I'm the worst person ever. I keep falling into big sins just to get by and feel okay. Every day I'm so lonely, and the internet is my only escape. This dunya scares me, and I've started having mental health issues that make me feel completely cut off from everyone. I remember when I used to be a really good Muslimah, and now I can't stand myself. I wish I could do better, but the loneliness is crushing. Living feels too hard, and sometimes I just want to sleep and not wake up. I'm done with myself and don't know how to fix this. I'm just so exhausted. Please, no private messages from brothers, just need to vent.
