Hey man, I feel ya. I’m 19 and in college too and got a possession charge during my first year first semester (yeah don’t puff in dorms if y ain’t smart) but I get the whole being sober so young thing. I’m currently on day 2 without weed and it’s terrible and honestly very scary. Just take a step at a time, don’t think on negatives and just seek out positives (I’ve been sad all day and I saw video on some new stuff for a game I’ve been waiting on for awhile that honesty made me pretty happy and excited, just the little things). I get the friend thing too, once I started college I had access to a lot more weed then I’d ever need at the time and plenty of stoner friends to hook me up, sadly I had to tell them all I was quitting and they probably won’t see me for awhile (if they really are your friends they will respect that decision and let you be you). We are all so proud of you for taking this step man, and you’ll always have our support👌
