Hi there ~
I understand your concerns. I am glad that you have not done any marijuana for a long time now and that you regret having done it in the past. I also believe that drinking alcohol may also contribute to your agoraphobia
or make your chest pains worse if you do not have a cardiac condition. You may also need to consult a psychiatrist
to get treatment for panic attacks as well as problems with appetite. You may be having symptoms of depression
for which a full history and physical examination is necessary. I wish you the best in your recovery.
I hope this helps. Take care and have a lovely day!
