Insane? Like in the membrane?

I haven’t posted in a while and I don’t respond to shit so I’d understand if everyone just waves this off. I’ve been hearing voices for a while now first I thought it was me just being stupid and it wasn’t constantly so I ignored it. I thought it was my subconscious for a while but then it got worse and I keep getting sharp headaches which follows by the voices. I still don’t know if it’s me just acting stupid or if this is genuine, but they keep getting worse and worse telling me to kill myself or to hurt others. I use to cut a lot and I’ve started again because it seems like the only way to stop the thoughts of hurting other. It happens a lot in public and I just usually just put earphones on and blast music or just scribble the thoughts on a notebook and blackout on what’s happening around me. What got me today was when I saw a homeless man talking to himself and I had like a panic or anxiety attack thinking ‘Oh fuck is that how my future looks like’ nobody knows this or maybe they just ignore me, but i feel like constant shit. If you read this thanks for listening to my ramblings. plz I don’t know what the fuck to do.
