Is it possible for someone to start thinking and reading about panic attacks so much that they actually get a full on stinker of a panic attack that can't all be in the mind (well, you know what I mean)?
I imagine that it is completely possible if the conditions are right. Ever heard of "penis panic"? Not exactly the same thing but similar idea. Your brain is a powerful thing.
I didn't wish myself pregnant but the more I worried about it the more I noted physical symptoms of pregnancy. Worry also through off my menstrual cycle. After 2 urine tests and one blood test...reassurance.
Yes I think you can think yourself sick just has positive thinking can promote healing and a sense of well being.
