My Life Seems So Unfair

I can't seem to stop always thinking about why my son was taken away from me. I find it so unfair that women the don't want children have them and mistreat them. I would have be a good mom, I loved my son so much from the very beginning. I get so upset when people say thing to me like "Everything happens for a reason" & "God already planned your life out". What good could possibly come from taking my baby away from me? I cant seem to find an answer to that. Everybody has tries to give me so many wise words about how my son was supposed to be taken from me, how this was the plan for my life. But nobody can tell me what good is supposed to come from my son being taken from me or why it had to happen to me. I feel like i'm a good person. I need something good to happen to me, I feel like I have no purpose to be here anymore because I want so much to be with my son. I just don't know what to do anymore.
