Who can be a trustee ?

After my mother died, I had to put the money I inherited from her into a trust fund so I could receive Social Security Disability  ( Don't judge me ) . After my brother died in 2003, I was able to buy a condo . The lawyer who settled my brother’s estate put my condo in my trust fund’s name . The trustees I have now are going too far and overstepping their authority and they insisted I move out of my condo so they could sell it . I absolutely hate moving, and I want to live in the same house on the same street in the same town until the day I die ! I want to replace my trustees . My current trustees are the only trustee service in town . My friend Marcia believes only another trustee service can take over . When I set up this trust fund, my lawyer asked me “Do you want your brother or your father to be your trustee ?” . My therapist said he used to be a trustee for one of his relatives . There are 28,190 people in my town . Do you mean to tell me in all those people, nobody can replace my trustees ?
