Vent? Disagreement over treatment and care for family member with paranoia

Hi moms and dads, it’s me again.

My cousin was having problems living alone and called 911 and has been hospitalized for 2 weeks now. His doctor said his conditions are going back and forth and not suitable to leave the hospital. We got his work stress situation somewhat under control, which was mainly what triggered his severe lack of confidence and trust towards others. Anyways. He was stressed for 3 days preparing for the call so I told him to rest and I wont visit him the next few days. I told my sister that too. She didn’t listen and kept visiting him everyday and kept bring more books and exercises for him to do (which he cannot do and will stimulate his brain more). He felt he is better the past 3 days and wants to leave but he’s not ready. He doesn’t accused the hospital of keeping him a prisoner and such.

My sister is trying to be supportive but she always stimulates him and encourages him to leave. That’s the goal but the way she does it makes him feel it’s wrong and a bad thing to be hospitalized. She doesn’t understand why I won’t let him have everything he wants, including his “freedom” to leave. Like wtf. He’s there cuz he’s going crazy and scared that he’ll take his own life so he willingly asked for help??? He literally was so deep in his imaginary world that he couldn’t work or take care of himself??? As in cooking, eating, showering, sleeping, etc. So yeah. Of course I’m not okay with him roaming the streets for 8 hours just because the doctor said as long as he’s with a family member??? I have disabilities myself, mentally and physically. I can barely manage my health, my life and take care of the senior at home. I don’t have the energy, strength, and time. I can’t handle him if he runs off or tries to harm himself or others. The hospital has multiple people to check in on him every hour. Last I visited, he said someone planted a chip in his head and everyone (other patients and families visiting) are spies taking pictures and videos of him. Like wtf is he gonna do if we take him to public or crowed places??? He doesn’t have a room to run back to when he panics, again. Now my sister is saying she doesn’t want to keep hiding my cousin’s situation from his mom and our mom, and will tell everything to his mom who had a brain surgery last year and mentally and physically can’t handle this kind of stress. I hate my sister sometimes. She only wants to care how she thinks he wants and not how he truly needs. He’s not capable of making decisions and she kept feeding him ideas like going out to play basketball. Like he doesn’t even remember to wear shoes when we go out for a walk in the corridors. Ugh. I’m ok dealing with his paranoia, but I don’t know how to deal with this sort of drama. Like how do we even make sure he will take his meds if he’s out that long? Why wouldn’t she listen to me and take him out gradually? First outing shouldn’t be that long. Seriously frustrated by all this.
