Whats Wrong With Me? Will I Feel Normal Again?

Im trying to figure out if any1 has ever heard of what im going through rite now. Like I dont feel normal like I feel like the euphoria feeling all day kind of. Like 2 weeks ago I smoked some weed and I tripped out and didnt feel normal. Well last thursday I think I felt normal again im really not sure but I did some cocaine and my heart felt like it was gona explode and the back of my left leg started to hurt and at one point both my legs had went numb. So today is like the third day and like all day I feel the euphoria and I just know I dont feel normal . Im kinda paranoid sometimes but not really paranoid. Like im not keeping myself in my house I still go do stuff I just want to feel normal and im scared that I might have !@#^ed up something and aint gona feel normal again. Im not hallucinating or anything and I will never do drugs again. People do drugs for years and are ok and ive only been doin drugs for 3 or 4 months maybe I my body and brain just cant handle them like everyone else. Well I will never do another drug again. I dont want to see drugs or smell them at all and I will never do drugs again. Like I was at a party last night and I smelt weed outside and I went right inside. I couldnt really enjoy myself though cuz I dont feel normal and I just keep thinking like this aint gona go away. If I dont feel normal in two weeks im gona go to a doctor. Well I was just wondering if any1 has heard of this or anything and if you think ill be ok and will feel normal again
