Hi there ~
I understand your concerns. Cannabis is an addictive drug and to kick the habit you need to consult a qualified substance abuse
who will provide you with the resources and help you through the withdrawals by having you admitted to rehab. I believe that your symptoms are all quite common in someone using these drugs and you would do well with the doctor's visit who will prescribe medications to control these symptoms. Please do not ignore as your life is at stake.
I hope this helps. Take care and have a lovely day!
