Where do I start with child support

My child has had a cancer and I my current girlfriend supported us through all the drama she was put through. She even supported me when I moved back in with here to help out with my son. Now my childs mother has threaten me with childs support if I continue my relationship etc, my current girlfriend keeps telling me to put myself on childs support but my mother says I will have to ge a lawyer. I do not have the funds for all that because of my son medical bills (cancer free at age 5). My current girlfriend left and went overseas military, recently back and we are moving back in etc. My childs mother screwed me on taxes where now I owe back.

I claimed my son in 08 because he stayed with me 8 months and her 4 that is when we seperated and moved apart. So when she found out I was with someone else she clamied him 2 months after me and when it was brought to her attention she told the IRSI did it without her knowledge. When I moved my mail never was rerouted from the apartment to my new address (current girlfriends) so I missed the IRS notices. Anyway for 2010 I let her claim him because she was out of work so much and I was still working and supporting my son, but if known they were going to garnish my taxes I wouldn't have let her. So all the sneakiness I need to put myself on child support and get visititation because she will keep me from him, that is who she uses to get at me. I get him Fri after school and she picks him mon for school. I NEED SERIOUS QUICK HELP.
