Feeling overwhelmed and scared about what's coming

Assalamu alaikum, this is a tough situation to explain. Without going into all the details, I have a mental health condition that makes things really hard. Someone said they'd get me in legal trouble and called me hurtful names, and it looks like it might actually happen. I can't afford a lawyer or defend myself properly because of my illness. The worst part? If they end up giving me an injection I don't want, I'm scared I'll lose myself completely. I wouldn't even be able to pray, repent, or do anything. I've neglected my salah and made mistakes, and my biggest fear is facing Allah's judgment without a chance to make things right. The thought of ending it all crossed my mind, but that would only make things worse. I'm just so lost and don't know what to do.
