Get some Xanax. That will stop your anxiety.
Pot helps, too. Though it does make a minority of people more anxious, so start with only a small amount.
I think it was pot that created my panic syndrome in the first place. Anything that has any chance of making a person worse should be avoided. It's not worth it.
Everything has some chance of making a person worse, so avoid all things.
But - since you have tried it, you thus have gained the right to knock it.
My experience as a young person who tried pot, was that it makes me extremely paranoid, and that's the last thing I would recommend to anyone having significant anxiety problems.
I don't use anything to treat any psychological problem except for problem-solving itself. If you are anxious, there is a reason for that anxiety, and it can be confronted head-on with adequate effort in the right direction. If you confront the problem and resolve the causes, the anxiety will dissipate. Same with depression. If you understand the basis, and not focus on the effects, you can eventually resolve the psychological issues which are causing the depression, thus alleviate it altogether. I'm not implying that it is easy, because the opposite is true. It's the most difficult undertaking of my life, and it took 12 years, but the cure is worth the effort.
