My mom has delusional disorder and I can't take it anymore. What can I do?

Your mom is relatively young. Some of the symptoms you mention can be that as a side effect of an antipsychotic, she has lost her filter.
Then, educating her about behaviors can help-she may be caught up in panic mode and not even realize she is way way over-stepping your boundaries, pushing you away more and at the same time fearing abandonment.
Someone prescribed the respiridol-can they talk to your Mom about boundaries for living together? Does she read still?

Jill, YOU need to establish boundaries, what you are willing to do and what you are not. Debilitating - at what level is she able to function, if at all, reason? Why do you stay? Mom would have to find help elsewhere if you were not there. Do you feel she is manipulating you? Maybe she is a narcissist with delusional disorder?

Is she open to getting treatment? I'd encourage her to get therapy and take any meds the doctor prescribes. That condition is treatable, based on what I have read.

However, how long ago was she diagnosed? If her doctor is not aware of some of the other symptoms that you are observing like, repeating, I would explore another consult...just to rule out another problem or underlying condition.

You are right in that caring for a person who is suffering from a mental health condition is stressful. It's incredibly frustrating too, but, I'd keep in mind that it's not their fault. They are ill and try not to take things they say personally. Maybe, after 3 years, you need a break or some help. I'd look into that.

she is 69 i am 27 she is not incompetent id say somewhere inbetween competent and incompetent her logical reasoning is wrong and things like that but she can make her bed and order food to eat & such. she has No boundaries though she will ask anyone anything or for anything she follows me interrupts me if im on phone with father shes taking risperdal morning and night i dont know about debilitating i looked up the meaning and it basically says weak? i dont know what you mean by that question so

There are medications for this. Ask her MD to prescribe some.

Jill how old is mom? How old are you? Sounds like you need to move, establish boundaries with mom. Is she competent? Is delusional disorder debilitating? What meds is she taking? A bit more information would be helpful.

Yes i have diagnoses. yes it came from a mental health provider, im not ignorant i dont self diagnose. yes at work i can leave her. she dont wanna be alone, i say il move out and come by everyday and she tells me "ill never do ____ again" whatever it is, desperate attempts obviously bein alone really agitates her. no she doesnt like the word Aid when im gone on vacation my older friend tends to her but thats a friend an aid makes her feel "disabled" she doesnt like listen to anything that infers she is sick or "crazy" u gotta walk on eggshells with what you say to her for cooperation with medication and so on. i was living with my parents dad retired and moved and im here with her so we moved together. i am in a difficult situation. shes inappropriate talks about my father to much to me how to get him back shes delusional about HIM

And why doesn't she get help? You have a diagnosis -- did that come from a mental health care provider?

It sounds like you can leave her alone while you work. Would she be OK on her own with perhaps some daily in-home help? Did you move in with her or her with you?

It sounds like you are in a very difficult situation. Please provide a little more information so we can make more specific suggestions.
