When we are kind, compassionate, understanding, some people will try to take advantage of us. They mistake the compassion for being a push-over, sometimes.
I am very sorry this has been your experience, thus far.

You seem so very sincere; this must be very hurtful.
Maybe you aren't paranoid. Maybe you are just on "high alert?"
I tend to be on "high alert" from past traumas.
Under certain circumstances, I'd also wonder about the cause of my flat tire, especially if I had someone telling me they flatten tires for revenge.
I have found you to be a great person, Seesaw. I think maybe you are too hard on yourself?
I hope you'll have some healing relationships soon!
