Hi Scopri and welcome. I'm sure this arguing back and forth is very unnerving. I don't know how you get to sleep at night.
While you may not be depressed, etc., I do think it would benefit you to see a therapist. A therapist could determine why you're not able to decide one way or another about issues, and why you're continually arguing with yourself over them. Logically, I would think that you'd HAVE to have an opinion on issues, but for some reason you're not allowing yourself to -- and a therapist could find out WHY.
So please have your doctor refer you to a good therapist -- he will know who to send you to. I wish you the very best. Take care and God bless. Hugs, Lee
