Scrupulous behavior

I am not feeling well.  I have been depressed over what I have done.  I don't deserve it.  I also have scrupulosity which is very hard.  I need help.  I know I need help.  I wonder if it is like obsessive thoughts about infidelity.  It is based on moral issues.  I ask for healing.  I am not sure if I am saved or lost.  My biggest fear is that I have not been saved by faith because I am clouded with so much doubt.  I am sure if it is the enemy or if it is a disease.  I am worried about it and there seems to be no end in sight.
