I can’t take ppls negativity

I want to know why my fiancé seems to be the only one I can go to and not be met with miserable replies? I mean this everywhere.. work, family, online. It’s always miserable. I feel I’m bracing myself and then we call and suddenly I’m happy for a moment. It really makes me want to run far away live alone with my fiancé away from everyone. I’m too tired for your misery
