Hi Just George,
Wonderful that you found God to be there for you. No, you do not sound 'New Age Christian', you sound like millions of ordinary folk who are trying to get to know God better, and to get closer to Him. Praying to Him 'just by yourself' is wonderful; don't forget that it's a conversation with Him, not just a shopping list of wants, but of course you can ask Him for all sorts. He is so approachable and generous.
As for which church to choose, I don't think you should be too worried about which denomination - all have their strengths and weaknesses, which is hardly surprising since they all comprise of human beings who are not perfect!The best guide is your own instinct. When you find a church community that is live and warm (not all of them are I'm afraid) and suits you, and helps you get closer to God, stick with that community. I wish you so well in your new life with Him, and I shall be praying for Just George. A warm welcome to you, good brother.
God bless,
CJR
