Meetups go a long way with healing. It is really the best meeting others with the same shared past. Many I've met still seek counseling for issues and advice, and it is best to see a counselor with experience in high control or cult religions. Most likely the counselor that specializes already has dealt with exJW's, and their issues are not unlike any other high control religion, orthodox Jews etc.
Anyone with serious issues needs to see a qualified physician or therapist. The success of meetups entirely depends on the people in the area, and their desire to meetup. Your mileage will vary.
We had a very vibrant group here about 10 years ago. Most have moved on, the conversation changes once you have sorted things out to a degree. I just spent an evening with Aude Sapere last week, she is one of the very first exJW's I met in person. We still have issues to sort, and appreciate the understanding ear of a fellow survivor.
With that being said, there was a very large turnout for Cedar's book signing, most I think were not on DB's, but but definitely informed with websites and youtube. I had a beach party one time and people came that I didn't know or engaged with on here, but they read the invitation and came. I also met many newly exited ones in Tahoe. They watched Eric's JW Struggle on youtube and just came not knowing anybody. Pretty amazing stories all of them.
My point, give it a shot! Post something in meetup and on boards. JWN used to be THE place for all things exJW, and I don't know if there are other places that people go to for information. Again, it just depends on the desire of those to want to meet. I wanted to meet people so I did, and it is great. Good luck!
