A Heartfelt Plea for Guidance After Family Struggles

Asalamu Alaikum, everyone. A couple of years back, I made a big mistake-in anger, I said harsh things about my mother in a message to a relative, exaggerating issues because I was hurting from our strained relationship and wanted support. My parents forgave me then, but recently, we had another argument, and things escalated. My mother reached her breaking point, and both my parents have now disowned me. They still let me live at home but have said they wish I were dead, cursed me to Hell, and declared they'll never forgive me. They've stated I can't attend their funerals, they won't come to my wedding or meet any future children, and they threatened to share past mistakes I was forgiven for, like inappropriate conversations with non-mahram men. I deeply regret my past actions, and I love my parents dearly, but they accuse me of lacking humility, being arrogant and evil, and just want me 'gone.' They doubt my faith in Allah, but I truly believe and am terrified of Hell-I feel lost, scared, and as if I'm already dead, awaiting what seems inevitable. Please, any advice would mean so much; I don't know where to turn or how to cope, JazakAllah Khair.
