I cant sleep!

Yeah ive smoked almost everyday for 7 years and recently just quit a week and a half now. I was fine for the first couple days then it hit me hard i cant sleep no more barely, i try not to think about it (weed) and i thought i was doing good my mind was starting to think alot more clearly but it's my body i guess!?! My body is all shaky and i've been having anxiety attacks.. at first i didn't know what was going on with me my heart was pounded out chest, i was soo dizzy it felt as if i was on a whole different type of drug or something. I went to the emergency to see what was going on with me and turns out it was anxiety, the first time i went to the emergency my heart rate was off the charts because i had no clue what was wrong at the time and was panicing. I'm still getting the anxieties a little but i know how to control them a bit more now.. I just cant sleep i try no to think but thats all i end up doing and i really hate it because i
'll start thinkin of everything bad, even suicidal at some points and i just wont sleep till my mind and body cannot stay up any longer! i sure hope this all ends soon
