Can anyone relate?

Hi! I am not really sure how reddit works but I am hoping someone can help or relate to my problem. I tried smoking for the first time when I was 16 and had the shittiest high, projectile vomiting and the worst disassociation for days after. Due to this I have always been the friend who doesn't smoke in my group of HEAVY smokers. I started smoking weed about 4 months ago and it immediately became an everyday- all day hobby. Since it is so accessible from my friends I haven't found myself sober since I started. I realized when I tried to stop I was the most anxious I have ever been. I was shaking and throwing up.. so I smoked again. I'm only 19 and I want to get ahead of this problem before it goes too far and I guess I just wanted to see if anyone else has gone through this? I have had severe OCD my whole life and it has never been worse. I feel like i'm spinning and fried out of my mind but I'm completely sober. My body feels weak and I am having migraines almost daily. If anyone else has been through this Im looking for tips on how to improve my mental and physical health during these weeks of recovery. XOXO
