A situation I had once that really worked well was I had friends with a very large house, from whom I rented a wing of it. People were there, but not in my face. I could dip in or out as I could handle it. Apparently I cannot handle being married. My separated husband is also a rager like me, so this does not work (apparently).

Our enviroment is crucial to our mental wellbeing. If you can't get along where you are living you might want to consider moving and finding a roommate. That's not always the ideal solution, however, if you have enough space and lay down some ground work it might help. Good luck

yeah, i had a good situation, and being bipolar I had a trigger and i lost it all. Now i live in a shit town with my mother.

I had quit drinking and drugging, and was on meds and saw my doctor regularly

now i drink, get high, don't take meds, and am stuck in a shithole town with people that don't get it. So what do i do about it? i don't know....but I keep trying

IT's not who you live with, it's how you live with them.
You don't have to announce that you have a "disorder" but rather, you should announce that you have a "lifestyle". You cannot tolerate this and that and that (whatever those triggers may be, list that you cannot live with those). and make sure you are living with someone that is either on your schedule or respects your schedule. For me, my sleep cycle is THE most crucial part of staying healthy. The minute my sleep is challenged is when I start wavering. My husband can recognize the signs sometimes and will literally force me the the bed and tell me to sleep. IT does a world of good.

How does anyone else deal with this one?

I feel for you. I had to move in with my parents at one time and my Dad through me out because I was drinking, it was awful, but fortunately I had someone who let me stay with them and let drink and abuse some drugs and took me to the hospital until I got better. Wow, that was one hell of a sentence. I also had to move from Nevada back to PGH. and still miss it. I live with my husband now. When I am stuggling with depression though, I SO MISS LIVING ALONE. I just can't deal with people. Hope you feel better soon and when you do maybe you'll be able to make a change. Good Luck

I used to live in a hotel

I haven't had a problem living with non-bipolars really...just kept my distance when needed. Of course, when very unwell it's a different matter. When you talk of being 'triggered' it sounds like an anger issue.

I wish I had some good advise. I lived at home until I was married. I used to be a professional Housesitter. So I was away from home more than not. It was kinda cool changing homes and "lifes" every few weeks or months.
Anyways I do know that living with someone who doesnt understand our disorder can add to our lack of wellbeing. I have learned that sometimes I have to quit trying to get those around me to understand. I have made a safe distance where I can interact and still remain in tact for myself. I find myself silently laughing at others now. I think man.. if they only knew.
Maybe you could make your own area like in your room, then like #4 said tell your step sister you are making some lifestyle changes. So you can feel better and do better.
I hope this didnt sound like a bunch of crap! Just saying what worked for me! I wish you the best!!

Thank you everyone for your replies. I don't know if I'll actually end up moving or not, but I don't want to feel like I have to be out of my home. I have tried explaining, tried setting boundaries. When I'm around my sister and my disease is really effecting me she says it stresses her out, and when I try to take myself away from the situation she thinks I'm mad, so I feel like I can't win. I want to stay in this house because I do really like it, but I feel like so much anger comes my way for things I can't control.
