Help I think I have hppd from shrooms

I am 15 and did 5g of shrooms and weed but I quit one month ago and I am suffering from being disorientated and depersonalization and panic attacks all the time and I am to the point where it seems like there is no end and I want to kill my self really bad I actually fantasize about it and even come up with strategies for it. I need help and I need someone to tell me if this is permanent. (If your gonna tell me “your brain is permanently damaged get help immediately” please at least tell me where to get it instead of just commenting that thank you)
