Mictar, I give you props for quitting weed , sounds like it was just making the problem worse. Self medicating is never a good idea.

I don't know what the general consensus is on the forum about medication, but it has helped me tremendously. I've done and felt everything you describe: thought I was dying or going to have a heart attack, been to the ER more times than I can count and had all the tests done!

My advice is to find a psychiatrist you trust and that you like... They can help you find medicine that's right for you. I know medicine isn't the answer for everyone, but that coupled with therapy is a great place to start. Even if medication isn't for you, just talking to someone and having someone help you develop the tools to handle anxiety is life changing.

You can beat it!!
