Hi,
Shared living can be hell. I have moved three times recently, and dealt w/so many wacky (to me anyway) issues/people that were painful, uncomfortable, etc.
Best thing I can recommend as someone who has SA, is to look for a place that is QUIET. Specify that the home is generally quiet. I did that where I am now, and I'm sharing with two people who are quiet type people. I am having problems, a little, but not big problems, and mostly it feels fine to me, and I am so grateful. The one gal, who I'm renting from, works as an accountant, very stable and normal and quiet type. The other gal actually is hearing impaired, which it seems makes her more sensitive and quieter. Most people aren't going to be on the quiet side, but if you search for this your chances will be better.
I moved to the place I'm in now in March. Before that I was sharing with two quieter, more sensitive type people, but the woman there turned out to be a bit of an angry monster-before I left she told me at one point she didn't want to have any more conversations with me. She was difficult. She chopped fresh vegetables and it was just a noisy, violent type of experience for me. She was a frustrated unhappy person, IMO. Also her partner was particular, and they were sensitive to smells: didn't like the smell of my coffee, smell of my popcorn bothered them. Although I had these problems I made the best of it, it actually became unbearable for me when another woman moved in-who was not a sensitive type of person. I felt victimized by her and the other gal, somewhat, and was insulted, sleep disturbed.
Place before that was bad too.
I like living with people, but working it out so it suits you is tricky. It is really impossible to know the little things people do that might bug you until you actually live with them!
