Are you in Therapy? If not you should , it would help you learn ways to commnicate maybe in a way the others would understand better?, or if they are still unwilling to step up and be more tidy you can learn ways to work around the fact they are slobs, you are not and how to keep yourself safe.
What does the person you love have to say about this situation? Will he/she go around and at least move potential hazards out of the way for you a couple times a day ?
I suggest you get a cane and when you walk about the place just use the case to push things aside. Sure that isn't going to be a very acceptable solution , But if you can't or won't move , your options are limited.
I'm sorry I hope a sensible solution can be agreed upon with everyone living there.
