We're sort of in the same boat. I'm 19 now, and I started smoking weed when I was 17. I never smoked that much, usually I would just smoke a jay with a couple friends, but the last two times, I smoked excessively. There was this one party I went to in October with a bunch of friends and we literally smoked all night. I took so much bong hits that it wasn't even funny. I felt so unreal and I became extremely paranoid and anxious and now that I think about it, I might of had my first panic attack that night. Then around mid June, I smoked again. It was around the beginning of July when I suffered an extreme panic attack at work, and ever since then, I haven't been the same. I literally spend 24/7 thinking about my health and what I could have and I spend hours on the internet searching my symptoms (which is a bad idea!) Lately I've been convinced that I have something more than anxiety. But I do believe that weed did attribute to my anxiety and depression, because I feel like weed did trigger my "anxious thoughts", which sort of caused my panic attack in the first place... if that makes sense. Often I feel so unreal and I suffer from depression and derealization, which is hands down the worst feeling ever. But I believe that with therapy and maybe the use of some meds that we can and we will get better! I have also lost some weight, but I believe that was due to my depression. Have you been feeling down lately? And a behavior consultant told me to practice "deep breathing" about 5 minutes a day to regulate how I breathe and to make me feel more relaxed. I wish you all the best and we will beat anxiety! Always here if you need me!
