My Situation

I got in some trouble in 2008 and I ended up going to the shock camp I did a total of 8 months and 180 days of that time in the shock camp. While I was in there my kids mother did not want to take care of our kids and my dad had them for a while and then there grandmother on the mother's side had them a lot. Well finally she took us to court for temporary custody and won of course because I was in jail. I have been out since April 22nd 2010... was scheduled to be on parole for two years and got off April 22nd 2011 because I did everything I was supposed to, early for good time or whatever... I have been trying to get my kids back since I got out!!!!! And this seems impossible, I don't know why it's so hard to get my kids back from a grandparent.... I also can't work right now because I stay home and take care of my father full-time.. He was diagnosed with lymphoma and was getting treatment wich took about six months.. Now he is going to be getting the interferon shots and that will be another six to twelve months before he gets done with that.. So I will be out of work that whole time... Just because I cant work and stay at home to take care of my father, does that mean I don't have a right to take care of my own children???? I'm willing to answer any questions anyone may have and please comment I really would like to know what everyone's opinion is on my situation....
