Hi there ~
I understand your concerns. I believe that the PCOS is related to the weight gain rather than marijuana. It would be better to have yourself treated for this with the help of an OBGYN
while your weight gain will stop by itself. I believe that your anxiety
disorder is also related to your PCOS, however please consult a psychiatrist
who is well versed with substance abuse
issues as well. I wish you the very best in your path to recovery.
I hope this helps. Take care of yourself and have a lovely day!
