Please help me. ):

I signed the Power of Attorney to have my son put in my aunt and uncles care on August 30th 2011. Nothing is finalized with the adoption and I don't want to go through with it. I raised my son from the time he was born, June 6th, 2009 until May 2011. May to August my uncle and aunt had him and were caring for him for a while. I had him in August 2011 until I signed over the POA. Since before he was born my family has been pressuring me that I can't do it (even though I was doing a fantastic and out standing job). I am a single mother so they think that I will never be able to provide my son with a good life. I miss him so much. I wasn't working before, just going to school and on state assistance so I can see where they were coming from there. But now I am working. I am a certified phlebotomist and trying to get a job doing that. I currently work as a cashier at a restaurant called Rubios. If I were still on state assistance I definitely would be making more than enough to support both of us. I'm so depressed without him. I've tried to talk to various family members to try and find help but they won't help me. They just brush me off because they don't want to hear it. My aunt and uncle who are trying to adopt him basically have disowned me, after lying to me about not having children of their own (she's now in her last month or so of pregnancy). Whenever I try to come over and see them or bring him books (he LOVES books, just like me <3 ) they brush me off, telling me either that they're busy or that "it's just better if you're not around." Mind you, this is all supposed to be a very OPEN adoption. Am I wrong in wanting my child back? How would I go about it? Where there's a will there's a way, right? I feel like there is no longer a point to life without him.... What do I do? I am very determined to get him back but I'm scared and don't know what the first step I should take is.... Please help me.
