In my case there are two main reasons:
- Family and all my friends are inside the Org. It's your whole social life.
- And not only that: you have no friend or support outside.
So yes, I could DA'd myself but it's a shock. I prefer trying to get a life outside step by step because it's not always so easy.
Add to that the emptiness yo feel once you discover the TTATT. At least in my case, I need time to make changes and accomodate myself to this new situation.
