It will always be in the back of your mind. In my opinion seeking help from a "group" set up is just swapping one controlling influence for another.
I know of some who have found professional help by way of psychologist to be helpful.
This site has been a tremendous help to me.
I have a few "worldly" friends that I have met along the way who I have told of my choice to leave the cult and they have been very supportive and assured me that I am not alone. These are proving to be real "unconditional" friends.
Find something you like doing, be it going to the gym, art classes etc and soon you will find yourself with friends who like the same things you do. It wont happen over night but it will happen.
