Hi Friend

It seems your mind is conditioned to expect something bad when something good happens. when such things happen then you will be scared if anything good happens as you afraid something bad is going to follow. People can't understand such things as it sounds voodoo for them. We people at this forum understand as we have ourselves gone thru it. please go to a psychologist who will listen to your problems and give you techniques to overcome this. if that doesn't help you can go to psychiatrist who can prescribe anti-depressants. if you want self-help there is tons of resources like yoga, meditation, relaxation techniques.
