Firstly you are not a sad individual. I used to suffer jealousy really really badly. I stil suffer slightly but not half as bad as I used to.
I had to realise that my partner was with me for a reason and that it was because he loved me. It took a long long time to sink in but it eventually did and we are fine. When I get that awful sicky feeling in my tummy through jealousy I just think he loves me, if he was going to leave me he would have done.
The more confidence you have the more attractive you are to the opposite sex. Everyone loves a confident full of life person so just try and think to yourself 'well what proof is there it won work out? Wheres the evidence she is going to leave'....eventually you can train your head to think less negative and more rational.
More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
