I am under so much stress I really think my integration is coming apart. Is this possible? !

I worked in therapy for 8 years to get better. I had 32 alters and they all integrated one by one......I am a man, 45 years old for those who are curious. My wife just recently told me she wants a divorce. She started meeting men via the MySpace.com place and since then has moved out. We had moved in with my 80 year old mother who can not live by herself. This made it possible for us both to go to college full-time. Suddenly all the plans I/we had are now totally different! I am so confused and lost. When I woke up this morning I had an erge to write on a piece of paper how my "system" looks now. I don't HAVE a system! I-ME-Uno-ONE! thats suppose to be my "system" CAn this much stress realy break all that work I did in the past back to square one? Anybody have answers?
