After I left the cult I was too scared to go to any churches for a very long time. I believe you can pray to god wherever you are, you do not need a building.
But if you want to meet with other christians the type of church I would suggest is one that is more evangelical, I started looking for one a couple of years ago and decided that if I was going to a church and they were going to be preachy and try and make me feel guilty and would be out the door immediately.
I live in Melbourne Australia and found the Hillsong Church, I enjoy going there because I love the singing, I don't really like the preaching bit, I got enough of that while I was going up in the cult.
I believe it is good to do mediation and yoga as well, as this aligns us with our spirit and gets us back to our true nature and self.
