Congratulations for overcoming PAD! That's awesome!
The reality is though, everyone's condition is different and some people cannot function without the help of medication and therapy. Also depends on what the cause was for your anxiety. If you have been thru a traumatic experience, you will need therapy and medication to deal with the anxiety symptoms. It's not easy for some people...it's not just "in their heads". Some have health problems, some are in very stressful environments and simply changing their thinking pattern is not going to "fix" their anxiety issues.
The thing always happens that you really believe in, and the belief in a thing makes it happen.
