Trust is an issue

I have done something unintentionally to hurt another perosn.
Fact is, I felt threatened by her.
I don't trust her.
I have an issue with trust.

I need to separate work and my live.
I cannot keep thinking of who is going to back stab me, make use of me etc.
I will go even crazier.

I dun feel good. The happiness is dwiddling.
I get frustrated... paranoid.
The threaat is there... I'm wary and on my guard.

She seems nice, but I have been betrayed and hurt by others. I just find her fake. I don't trust her... yet I have to work with her closely... I dun get good vibes.
Not keen to play politics.. but who is playing whom?
