Hello newagain, posting here is absolutely the right place, along with any other SR forum that you want to say hello and reach out to.
Good for you for wanting to live a better way of life. I had to lose many relationships before I 'got it.'
As for praying, I think God answers us all in different ways. It's not like a bright white light shoots out from the sky every time we pray - it's about developing a relationship with Him.
Something, whatever you choose to believe, brought you here, no?
Welcome and continue to share your fears, doubts, triumphs - this is an awesome place to be.
