I recently discovered the show 90-day fiance, while i had the flu.
I have to say that I was disgusted that such people are featured on television. The Americans featured on these shows remind me of women, who write to and sometimes marry prison inmates. They are sad, pathetic and unattractive.... but instead of working on themselves, they choose to whine, cry and moan that "no one / (fill in the blank) loves them".
My suggestion to these people would be this:
1.) Stop allowing the world to mock and ridicule you;
2.) Lose the excess weight, if that is one of your issues;
3.) Learn how to prepare your own food;
4.) Exercise - in addition to managing the weight, it will cause the release of endorphins, thereby improving your self image;
5.) Sit with a professional so that you understand the underlying causes of your lack of self-worth, so that you can address them.
