I feel so different after only 3 months of drugs

I’ve done meth , xanax, percs , shrooms, weed, coke & ecstasy all in under 3 months. My head hurts so fucking bad idk what to do. It’s like a tight pressure in my head . Sometimes throughout the day everything goes silent, my vision goes blurry a bit and i start to be really in my head. Like i don’t even feel real , my brain literally feels fried. I’ve only been doing hard drugs since october, will this feeling ever go away?
