It is possible that you may have an anxiety disorder. That possibility may frighten you but you have nothing to be afraid of. Anxiety disorders are very treatable conditions. Hundreds, if not thousands, of books are available on the subject. In addition, many individuals who undergo treatment learn how to control their anxiety and others become symptom-free. For those willing to seek treatment, the prognosis is excellent.
You have been dealing with excessive feelings of guilt. One aspect of the problem is knowing when it is appropriate to feel guilty and when it isn’t.
There are times when feelings of guilt are appropriate. For instance, if you have done something wrong, then it would make sense to feel guilty. If you have done nothing wrong, then you should not feel guilty. It is either appropriate to feel guilty in a situation or it isn’t.
It is important to analyze every situation from a logical perspective to determine if your feelings are in line with reality. Accurately perceiving the reality of a situation would significantly reduce or eliminate your anxiety. A therapist could greatly assist you with this. He or she would analyze situations that prompt your guilty feelings and help you to determine if they are appropriate.
Worrying about past situations is not useful. Worrying changes nothing. No amount of worrying will change or alter the past. Analyzing one’s behavior to determine if mistakes were made is a worthwhile effort. You cannot change the past but it could help you to know how to behave in future situations.
You mentioned that you have tried therapy. It was not successful but you should try again. Not all therapists are created equally. That therapist may not have been helpful but another one might be. The find help tab at the top of this page can help you to locate a mental health professional in your community. It would be wise to choose a therapist who specializes in treating anxiety disorders. I wish you the best. Please take care.
