Hi there ~
I understand your concerns. However, it is not at all okay to take any of the substances your mention, meth, diazepam
or marijuana to help with any issues that you may be having. I believe that you have a problem with dependence on one or more of these substances. You will also do well with consulting a substance abuse
counselor as well as a psychiatrist
for your issues with dependence. I also think that you will have to consult a qualified neurologist
to help with your issues. I hope this helps.
Take care and have a lovely day!
