I believe in God, and I consider myself a Christian. I went through a period very similar to yours. When I first left the organization, I didn't know what I believed. I was very frustrated, confused, and at times, anxious. I continued to pray for guidance despite my confusion. I now feel somewhat confident in my faith, but realize that I don't know a lot of the answers. I try to avoid dogmaticism and keep an open mind. But, I feel closer to God and a stronger faith than I ever did in the Watchtower.
I think that there is overwhelming evidence that there are spirit forces. I have a very close friend who dabbled in witchcraft many years ago, and she told me of how she had been repeatedly harassed by invisible forces. I have also heard others personally share similar experiences. I think one area that the Bible does provide very good advice is in avoiding all forms of spiritism (mediums, black magic, witchcraft, voodoo, etc, etc.) I have never known or heard of anyone benefiting from practicing these things.
Personally, I do have faith in the Bible, but I don't believe in inerrancy. I believe that many accounts in the Old Testament were allegorical (garden of eden, Noah, Balaam, Jonah, Job, Samson) and intended to be literary works which teach moral lessons. Some of them are obviously mythological and paint God as insecure, jealous, arbitrary, and cruel.
Whatever your jorney takes you, I would be patient. It takes a lot of time. Have you read the book "Combatting Cult Mind Control" by Steven Hassan? If you haven't, I strongly recommend it. It does an excellent job in explaining and untangling the indoctrination and mind control that groups like the Watchtower used. This book is a very good starting point. I think the biggest hurdle is overcoming the image of Jehovah as this cruel, angry, punishing God that we were raised with.
The best prayer that I ever uttered was "God, direct me and show me what to do". I feel that I was lead to a wonderful church with wonderful people. They truly manifest Christian love that the Bible talks about. But, that is just me. I realize that you will have your individual path. Your path needs to be your own, and not someone elses.
