So I don't really know where to start and don't know if AIBU is the right place to post, it's such a difficult situation, and I feel like I am totally alone.
My sister has severe autism, anxiety, OCD, obsessive controlling behaviour, learning disabilities. She is 33 and her controlling behaviour, anxiety and OCD has become progressively worse over the years.
I don't even know how to describe it, I literally couldn't put into words how bad her need to control is. She lives with my DM who herself has health issues but is her 24/7 carer. By 24/7 I literally mean she can't sit in a room on her own without being ordered around by my DS. She has an obsession with controlling her, and won't let my DM sit for five minutes without shouting more demands at her, and believe me half the demands she shouts at her she is perfectly capable of doing herself.
She won't leave the sofa, my DM has just had an operation and she has limited mobility but still has to come straight to her when she shouts.
When I say come straight to her I literally mean she has to drop whatever she is doing/ and go straight to her because she screams the house down and is incapable of waiting one minute otherwise she is fuming and makes it worse for my DM.
She also has intense jealously if anyone else speaks to my DM, we can no longer call her in the evenings because it's absolutely impossible to have a conversation with her because my DS is screaming at her to hang up in the background.
I feel like there is no support out there, we have searched for so long, I even contacted numerous private specialist psychiatrists who have told me they can't help with her because it is "beyond their capabilities".
She is with a disability psychiatrist but doesn't understand how serious it is, she just thinks we exaggerate and says it's minor OCD because of her autism. I have OCD, this is not minor OCD.
I won't begin to explain about her OCD or anxiety stuff because this post is already too long, and I wanted to explain about the controlling obsession because I wanted to see if anyone out there has any sort of experience with this because I am at a loss and can't find anything online.
I don't know why I'm posting this, I suppose it's because there isn't anyone I can speak to you and lately I've been worried and fearing for the future, if God forbid anything happened, although there are 5 siblings I would be the one to care for her, I have promised my DM because her biggest fear is her ending up in a home and the other siblings wouldn't take her in.
I guess recently I've been scared because she is becoming so bad I fear it will be completely unmanageable, and she will start controlling me to that extent and I can't live like that, she already tries and the only way I can describe how I'm feeling, as awful as it sounds... I feel suffocated. There is so much pressure on me all the time, and there is already no help and I feel.... scared.
Sorry this was so long, and thank you for reading, even if only one sentence.
