Can I sue a non-profit organization for invaded and violating constitutional rights?..?

I believe that my daughter's family are behind it: They're trying to forced me out of the state. Her relatives are well-known in their hometown. My record and rights were violated by an associate of the family: This person is a case manger who handles the homeless status(of individuals that are recovering from job lost,eviction,drug abuse). I am waiting for a scheculed date to take--dna's test.(DNA's test will reveal if she's my daughter,or not. I feel as though I have been set up. Want justice for premeditated destruction of a person livelihood. Please take or steer me into the right direction to get justice.
