Good luck with the move. I think you will find it both liberating and stressful as you adjust. As of triggers I do all I can to avoid stressful people, exercise, do fun things and find my own routine. I also live in a 2 bedroom flat and it is enough for me. Unfortunately, I can't have pets, which I would love but I cannot afford a place that allows them. Most importantly, be yourself and get comfortable in your own skin. I find that reduces triggers a lot.
