Bad weed and caffiene experience and dealing with anxiety

Alright so I've smoked weed before and it was all good it was a fun time. Nothing really happened I only felt a little rush and got hungry a bit after but it was all good and over all a fun time. Just recently however I decided that smoking is u healthy so I got some edibles. I accidentally took a lot, especially for someone my size I know I've taken a lot. So when I took the edibles it started out really fun, everything was funny and it was just a rush. But it didn't last long because after an hour into the high I started to realize I couldn't focus and I started to get paranoid and anxious. I literally sprinted home and told my mum I was going to sleep even though it was only afternoon. So in my room it was a horrible time I thought I was gonna die, I couldn't breathe, I had an extremely dry mouth and every ten minutes or so I get my body buzz on and off and I couldn't remember things I'd do five seconds prior. I would literally walk to the bathroom and not remember how I got there. Anyway I made it through the night but the next couple of days after I still felt a shortness of breathe. But two weeks after I was completely fine and normal again. Then one day I randomly decided to drink a lot coffee ( which I'm not used to) and I'm not sure if it was the caffeine but later that night I had an intense massive panicky attack and I thought I was gonna die again like the same feeling I had with the edibles but this time 100x worse I really thought I was suffocating in air. It's been like 1 month now since the massive panic attack and a little over a month since the edibles and ever since the whole coffee ordeal I've been dealing with almost crippling anxiety and breathing problems though I know my oxygen levels are fine and sometimes things don't feel real like I'm still high or it's all just a dream. It has been getting better and better like I remember I would have days where the whole day would be a constant struggle to keep my sanity and focus on my breathing. I really do feel like it's getting better and less intense and constant but sometimes when I get that little panicked feeling here and there part of me still worries that this anxiety is now permanent and I will never go back to my old self. Any help please is truly appreciated.
