Hi Julia,
Moving on is important, but being a JW will always be a part of who you are now.
Personally, I wouldn't DA because that's still playing by their rules. But that's just me. Many here have and said that gave them closure.
That being said, I really do believe that seeing a counselor is a great idea. It helped me. It is hard to find one familiar with ex-cult members, but if they're really good at helping people they can still help you. I worked with one for about a year. I gave him Steven Hassan's book to read (I recommend Releasing the Bonds) and that helped him to help me.
Best wishes,
Oubliette
