I am 73 yrs old and my son is 52. We live on a small piece of land in my trailer house. He owns 1/3rd of this land. The problem is that he has brought drugs, hard liquor & pornography into my 1972 trailer house; and when I complain, he destroys something I value. He has given me a list of what he expects showing I am to carry ALL financial responsibility. I feel threatened and carry my purse with me at all times, even have hadden some valuable jewelry. I am depressed much of the time feeling hopeless and helpless. Is there anything I can do to stop this before it gets physical and/or my mental/physical abilities decline to the extent I would not be able to?
