It IS abuse
I've been mocked and belittled every day that I'm around my BPD family member. Put down because of my health and appearance (I'm physically disabled) They suddenly and unexpectedly try to make me jump like creeping up behind me, sudden hand movements to within an inch of my face, with full knowledge that I have PTSD from some very frightening stuff that's happened to me.
I felt so down this morning I couldn't stop crying so I went on a web chat with a mental health charity. They said it's abuse. Which it IS. Although I know it's not the done thing to say about persons with bpd which makes getting help for myself really hard. The person on the helpline even suggested I contact a DV charity.
This is my almost adult child not far off 18.
