Suggest Treatment For Numbness, Anxiety, Insomnia And Depression Inspite Of Quitting Smoking

Hey I m 18 usually extreamely athletic, and pretty smart but I ve been smoking allot since my semi accident that happened toward the every end of summer and it took me out of football and hockey but I still worked out a ton so I always cleaned my system easily. Any who since the crash I started smoking pretty consistently but had some breaks here and there I ve never had a problem with weed. But once I stopped because I wanted to be as healthy as I Could be for rugby, I felt Different. Like a sorta numbness, FeeLing like I was still high but not as much, feeling somewhat dizzy, and I started having some crazy anxiety, insomnia doc put me on ambien and some anxiety meds and im taking Wellbutron.. but I only get 4 hours if sleep with it.. i fell asleep around 12:00 woke somewhere at 4 something and couldn t fall asleep and had to go to school witch I did, but my head felt like it had pressure in the temple the left side on my forehead but it faded as the day went on. I kept thinking that SometHing is seriously wrong with me, I even went to the hospital and got blood test, checked for fever, etc. And I m healthy. I still feel strange. Mom says its my health anxiety, and seasonal depression, but im not sure... I do feel better when im out side, and when I workout, it does feel like its going away, slowly but im just frustraighted becAuse im not 100% WhAt s wrong with me. I do have add but I don t really feel myself right now.. am I just detoxing, cleaning my system or whatever you call it? Or is there something wrong with me? Or is it really just anxiety?
