Anxiety is not caused because you are a weak person in either mind or body. All of the members here in the forum have some type of anxiety so we know where you are coming from.
No one knows what it's like to go through an anxiety disorder unless they've gone through one themselves. And, of course, it becomes even harder because for many of us there is no one to share the pain and the victory with who will truly understand. Joining a support forum was a wise decision so keep on talking to us.
Perhaps going back to therapy is something you should consider.
