What happens if my adult children try to seek guardianship over me (their Mom), but they haven''t had anything to do with for the past 8 years.

8 years ago there was an incident where I felt betrayed and it destroyed my trust with my daughters/family. We have talked about this many times and I have explained that I they just need to tell their side of the story. They just want me to "forget it". I was the one that was hurt and I feel if you can''t trust your family, who can you trust? I was given a mandatory referral from work Oct 2010 (a manager told me back in 2009 this was going to happen, he said my Co was trying to help me. When I asked what my disability was going to be he said ¿paranoia is sweet¿). I was told that I had to do whatever the Drs told me in order to be compliant, or I would lose all my benefits. I signed release papers for the Psychoanalyst to speak to my daughters now he can¿t find them. My daughters told him I was ¿paranoid¿ that¿s how I got my title. Now that I have a mental illness history, I feel my daughters are trying to gain guardianship. How can I protect myself, My home/asses are all I have.
