How do you deal with the STRESS?

So, how do you deal with the stress of being a parent of a child with special needs? I remember, at first, when Faith was first dxed, I thought I would just bully my way through all the chaos. I would MAKE myself be happy, MAKE Faith be OK, MAKE our family be normal, if I just set my mind to things and remained positive. As time has gone on, Faith has gotten older and more things keep surfacing. It seems to have gotten harder and harder to keep up appearances and my resolve. Sometimes, it feels like I am drowning in a sea of doctors, therapists, medicines, dx's and bad news. I think "How am I supposed to live the rest of my life like this?" How do you deal with all the chaos?
