Hi there ~
I understand your concerns. I believe that the first time you used marijuana you started to like it and it was the reason you started to crave for the same feeling and used the mixture? from a different person which was probably laced with many other chemical substances. I strongly advise you to stop using these substances as it seems like you have a tendency for substance abuse
and possibly dependence. I also think that you should head to the ER and tell them your entire story, and they will be able to help you out with the appropriate referrals and treat you symptomatically. However it would be best for you to stop using the substances and consult with a psychiatrist
who can treat you for the dependence issues and also suggest alternatives. I hope you do so as soon as you can.
I hope this helps. Take care and have a lovely day!
