Guilbert, I think you are being a bit harsh, and more than a bit sarcastic, referencing the Jeremy Kyle show. The post is difficult to read because of the lack of sentence construction or punctuation, but that can be how a stream of thought is expressed when a person is distressed.
My advice to Marilyn is to try to concentrate on people who treat you well, and to walk away from those who abuse you. You need to find worth in yourself before others will find worth in you. Maybe your own lack of self-worth is what leads other people to feel they can treat you badly. if you let them see that you will not put up with being treated badly, they may be less likely to do so.
Of course, it is not easy to develop that kind of confidence if you have been lacking confidence all your life. Are you in a position to be able to find some counselling? Even joining an online self-help group might be a help to you.
It is a great credit to you that you have not lost your faith in other people. Try not to dwell on the wrongs that have been done to you. That will only bring you down and make you depressed.
Good luck.
