Same.

My mum always thinks people are trying to hurt her and bother her. It just makes her agonise so much that i have learnt to think a bit differently.

Assume innocence but even if someone is being a bit malicious, just ignore it. It if actually starts bothering me, then i address the thing head on and ask the person if they meant to hurt me. They will obviously say no, but most probably, won't do it again. If they still persist, i cut those people out of my life.
