Sunshine,
To be honest, I'm not quite sure what I can say to encourage you.
I offer my condolences on the passing of your parents.

It sounds like your grief counselors are wise in suggesting you stay away from these people who are hurting you--or keep them away from you.
Many times things like this happen after there is a death...family members become angry and bossy and selfish. I don't know if this is what is happening to you, but I'm very sorry for it.

Are you able to stay away from them? Can you give yourself enough time so you can grieve and start becoming more at peace?
It may be hard for you to do it, but perhaps it's the only way you will be able to stop them.

My best wishes,
Cap
