Hello! I can understand your distress.
You have been using the drug for 2 years. It is a long-term use, and needs complete health assessment for the damages, to the body and the route which you used, like inhalation or
smoking. At your age, the Cardiological health should be checked thoroughly.
The drug you named is highly addictive. If you have stopped the use suddenly, the physical and psychological dependency may cause relapse.
If I was your treating physician, I will advise you to consult professional
de-addiction centre and enrol for a residential program. The
rehabilitation involves many specialists, for a successful recovery. Most important is involvement of your family/close relatives/friends/loved ones, who will maintain the drive for deaddiction.
Professional centres have counsellors, who take care of the psychological reasons for addiction, and counsel the family to help you. Interaction with others in the centre also helps a lot.
Please be patient and continue the efforts.
I sincerely hope for your recovery. Please feel free to consult for any help.
