Help me see my son

When I was younger I was not in a good place in my life to care for my son the way he deserved, so I made a hard choice to let my aunt and uncle care for him while I could not.  Since then I've unsuccessfully tried to see my son. In the mean time they have allowed my son to think they are his parents and erase me from their lives. I have been trying to reconnect with my son and let him get to know me again, but my aunt and uncle won't allow it. We are now taking this to court and my uncle is trying to take my parental rights away so they can become my son's parents on paper. My uncle has the means to drag this out and I do not. Please help me raise money to have the opportunity to see my son again. He is my world and I would do anything to see him again.
