My mom is 58 y/o and lately has been argumentative, suspicious, aggressive, emotional, controlling, cursing etc. It has been hell for me. She was really sick in the past and we all live together ( mom,dad, brother and me ). She has RA and is on prednisone for about 5 years. It's a small dosage ( 5mg) and leave her pretty agitated, but on 4 mg she get pretty stiff. Looking on the past, she always had those symptoms, even before the RA, but lately they are getting worse. She's always trying to get in an argument, cause she wants to win, kind of a childish behavior, one time I stand up to her, she got physical on me. Now I have to keep calm and just leave the room, to not let things get worse. Aside of the physical and cursing part, she kind of always was like that, but things are getting out of control. I've trying to get help from my dad and brother, but they don't fully understand the situation, and sometimes loose temper. Rheumatologist Dr. is trying to lower prednisone dosage, to see if it is a side effect or early dementia. She will not be back to her neurologist, cause on last appt she notice that dr. was suspecting of mental illness and she left the office. Those more aggressive and non sense behavior started about 5 months ago. I am getting crazy, cause I have no idea what to do. We ve always been close, I dedicated my life to being close to her, but now I think I was induced to that, cause I can see her manipulative behavior. I always thought we were best friends, and my brother acted the same way. We were pretty close and now I notice that destroyed my life. I'm trying not to be hopeless, and thinking about seeking help for me, to be able to deal with that. We came from another country, we got no family here.To make things worse, we all work together, and it's being impossible work with her. I got a younger brother back home, who is more capable of understand what I'm going through, but the geography doesn't help at all. I really don't know how to deal with that, i got a fertility issue ( seeing a dr. )and she's throwing my fertility issue on my face every time that she gets upset, and that has been happening pretty constantly. She goes all the way to hurt me. I'm hurt, but I know she's not like that by option, but I still don't know how to deal with that. Should I get psychological help for me? I don't have anyone close to talk, and I want to keep my mind health, I'm afraid of not being able to deal with that, and have mental issues myself.Has anyone have / had similar problems? If it's early dementia, should I think Alzheimers? Any inputs would be appreciated. Sorry for any misspelling, English is not my first language. Thank you.
