You can access a forum called NANCM (National Association for Non-Custodial Mothers) and get more help there.
I tell alot of people about them, because they are a very well organised group, with lots of well established and supportive people to specifically mothers in your situation, (as you can tell by the name) even though I've recently "fallen out" with some of their leading members.
I will just say this to you, as you've tried to point out to us that "mothers lose (custody) too", many of us fathers feel we managed a reasonable relationship with our children although we were allowed less time with our child than you are being given. We missed seeing our child open their presents on Christmas, and in my case ever being allowed to just pick my daughter up from school, when I felt like doing so (or ever in fact). However, that didn't stop our relationship from flourishing. It took much more than that, including false or trivial evidence from our ex.'s and our child being accepted by court officials, officials who were themselves all too ready to lecture us as not knowing or being what was best for our child.
Inpite of all this fathers are not to see ourselves as victims of this system (not that we really want to be victims you understand), the children are the victims NANCM leaders insist. That point of view, multiplied and re-enforced by our government's most powerful institutions, is enough to keep so many fathers experiencing your situation or worse as I've said.
