I had a hard time really feeling anything. Not happy not sad, nothing. The therapist I went to said that sometimes kids brought up in cults have just shut down their emotions because it was all too much for our little minds to deal with.
You're not alone, it looks like quite a few of us have the same experience. It took me a few years to make progress in this area, I have been out 17 years, and I am happy, have passion, and am at peace with life. Don't let your upbringing be what defines your life now.
Good luck and welcome.
