Help pls

My mom died a few days ago I miss her so much I can’t take this it hurts that she is gone I wish that I could see her again I just need a way to cope or just some better ones I started cutting again and started having really bad panic attacks and I tried to talk to my dad about it and how I feel but he doesn’t care and I’m trying to talk to my brothers but they act like it never happened and I just can’t do this anymore I want her to come back I don’t want to feel like this I need her to come back
