I'm way too suspicious, what should I do?
My past has made me who I am. Many people have let me down; I have often been cheated on, betrayed, and bullied.
I've become totally paranoid and distrustful these days. I easily become skeptical and immediately assume the worst. Unfortunately, this also ruins my chances with people who don't mean me any harm.
What can I do?
make a therapy. And learn not to blame others for everything.
Once is not a time, but twice is too much. That is, if you have often been cheated, then it is obvious to ask why you have been cheated so often, or why you can easily be abandoned. It is to be assumed that the reason is to be found in your behavior or personality structure. A psychologist might help you solve this problem.
