What has created all of your negativity?
Some understandable ones could be:
1) sexual molestation as a child.
2) major deaths in a family.
3) complete loss of home or shelter.
4) death of a child.
5) terminal cancer.
You asked a few questions at the end of your post. Those are perfect questions for a therapist or psychologist to review with you.
I think we all have had disappointments in life - some rather major. Most people here have had at least one of the five items listed above. Many have had at least two of the above.
We are here to listen ...... but YOU are there to do something about it!
Peace and wellness
