So heres my story: I'm 24 years old and ive been a light cocaine user for the last 4 years and i'm also a good drinker (social) and an occasionnal weed smoker... But never been addicted of any of these. 8 months ago after a partying night i was really drunk and me and my buddies went to do cocaine... It was good stuff, too good! So i went to bed but it was impossible to sleep so i had the worst idea of my life: i smoked a fatty all by myself... After this it was a nightmare and i thought i was going to die, i thought like if i don't die i'm going to be  ill for the rest of my life. But i survived and the next day was no so bad actually. 1 months after the badtrip i did cocaine again and i was sick the next days but with some strange weakness and anxiety crisis.. But everyday since then ( almost everyday ) i feel dizzy with pressure in my brain and sometimes it feels Hoooorible. But its not the only thing because i had like 100 other symptoms and i really feel depress at times .I also stop alcool and cigarettes because i just can't tolerate them anymore, if i drink the 2 following days feels like hell. So since this day my life changed drasticlly and i can count on my hands the days i felt very good. I went to a lot of medical test and everything is normal. Seriously i don't know what to do and i just want my life back so any advice will be more than welcome. Btw sorry for my english i speak french usually. Thanks
