I’m contemplating ending my life.

I’m tired of living. I’ve failed at so much, I still live at home, I’ve lost my mother, I’m in fear of losing my father next. im still a virgin, with my own sexuality issues, I’m bisexual and I’ve struggled with it since I was 13, and I’ve never had a girlfriend, nor kissed a girl. I never told my mom I was bi, and still haven’t told my dad, it feels to awkward and unnecessary to share that part of me. I have no friends of my age in my city, no career, no job(although I tried my hardest at working at an amazon warehouse last year), and my weight has gotta up to 483lbs, the heaviest I’ve ever been.The death of my mother has ruined me like I never thought I could be ruined ever before. What is the point in living anymore.
