Wifes Depression, Anxiety & OCD

I feal like my wife has all the symtpoms and signs of depression, OCD, Anxiety and Explosive Vulgar Anger Explosions (Screaming.)

I am no medical doctor and I do not want to give a diagnosis but, she has said in the past that she has Bi-Polar, Anxiety, Depression and OCD.  I am not sure what to do becuase she is really good at twistng things into me being the bad guy.  When she gets a little frustrated or upset her whole personality changes into this vulgar, angry and viscious person.  Once that starts I try to stay out of her path but, that gets me into trouble becuase "It shows I do not care..." and "Your abusing me by not helping.."

We have gone to marriage counseling and it seemed to go OK except I felt like she was lying and not telling the whole truth about things.  It basically turned into a me head down (sulking) while they "girl talked" about my "insensativity" and even laughing about it.  I think this is the first time I attempted to actually write about her and how she has made me feal.

We have 2 young boys and marriage dangling by thread.  We split up once and are now back together.  Her excessive cleaning has gotten to be out of hand (I mean EXCESSIVE everything in the house must be bleached cleaned and done HER way or I am purposfully doing it against her.)

I am not sure but, I have told her she needs to get help but I have said that in other words... "I will get help on my own and you get help on your own so we can work on ourselves then we can understand "I" and move forward."  When we did marriage counseling I had to set it up and get it all figured out.  Now I am afraid she wont do anything for herself...

I feal if something isn't done soon we will divorce.
