Idk what to do

I put my Bby father on child support the day I called Medicaid and told them my son was born 5/31/2015 , the lady I spoke to said if I don't the court sanctions me and my insurance food stamps would be taken away . Now me and my baby father are back together and I don't know how to tell him I put him on child support .. I recently found out I have carpal tunnel in my right hand and I've been seeing a chiropractic with my insurance . It has become harder everyday to do simple things like cleaning or holding my son . Idk what to do I don't want him to leave me. How do I tell him ? I chock everytime I have to tell him then I say nothing wrong
