There is some kind of mental illness that seems to run in my family. It appears to come down thru my father and his father before him. I do have a 52 year old son who is on military disability and 3 weeks he had the flu so badly he couldn't take his medications. I saw a full blown bipolar episode and it scared me terribly. I am living in his home with him to help him because his wife died from cancer a yr and a half ago. When he is taking his medication is sleeps most of the day. Some days he says he feels just awful and other - never wants that to happen again. Now, I have a son who at age 34 committed suicide and had 6 different personality disorders. One of those disorders had to be bipolar from the things that happened in his home. I also have a 40 year old daughter who at around age 13-14 started having a problem with me. She started writing terrible little noted and leaving them on my pillow quite often. We both loved horses so that helped her use up some of that nasty energy she threw at me. All these years she has treated me badly but not many other people except her brothers and me. I am now 72 years old and she was wanting me to move into a basement app't they are building but because of the terrible things she says to me. Her dad and brother were killed in a field with a sprinkler pipe 37 yrs ago when she was 3 yrs old. The brother that committed suicide was 9 yrs old and saw the whole incident. He also started acting mean and up and down with his personality at around 13-14 yrs old also. The son who was 6 yrs old at that time has a brain tumor that discovered when he was 27 yrs old. He never showed the same personality traits as his brother that committed suicide but there were a few problems. After over 14 yrs with the glyoma (spelling) tumor so deep in is head he is doing fairly well after radiation and chemo therapy. I can see where his depression can come from but he is pretty good most of the time. Why would the one son and daughter start changing personalities at around 12-14 years old? Karen...
