I am so sorry to read what you are going through. I am a 2yr breast cancer survivor and my H also blindsided me with D papers, but I got mine in the mail!
IF your H has left the home...In my state, there is a number you can call about getting child support. I don't know where you are at but you need to check and see if they have something like that...they will get on it immediately (or as fast a state government moves!)
I did retain an L who talked me into counter filing. The reason for this is that my H was having an A and gave me an STD plus, health ins, as you know, for us is a ridiculous amount and my job does not offer itso I will be asking for extra support in addition to child support. We are also asking that H pay for any of my legal fees. Counter filing allows a court date to be set and a judge to decide everything. It also allows me, if for some reason my H decides to withdraw the D papers, to go ahead and file IF I want to.
First and foremost...check on that child support and get that going!
