Hello & Welcome, CoffeeAddict103!
You are in great pain and turmoil (I know; I'm stating the obvious). You are not in a good place to assess and judge the past. Have you considered seeing a doctor or therapist?
Are you familiar with
relaxation techniques? You may be too upset to employ any of the techniques on your own. Is there anyone in your life who could help you simply relax?
Please keep posting.
