I spent about 8 months with a therapist while I was still married. Most of my time there was spent trying to save my marriage, but some of it focused on assimilating into society and developing normal relationships with normal people and getting past feeling like an outsider or worrying about being seen as weird or whatever else.
It definitely helped - just the practice of talking to a "worldly" person (the therapist/counselor) can help.
First, if you're facing severe distress (thoughts of suicide or depression/anxiety that makes it difficult to function on a day-to-day basis) you should seek help right away - waiting will only make things worse and could be life threatening. You don't seem to fall into this, but I just wanted to put that disclaimer out there.
Assuming you're doing "ok" but just want help to move forward my advice would be to first make sure you've educated yourself on how the cult has controlled you and ways that it's influenced you that you might not realize. Books I'd recommend are freedom of mind or combating cult mind control (Steve Hassan - probably would be fine with one or the other), and EXiting the JW Cult: A Healing Handbook - this has a lot of helpful stuff that's very JW specific (written by a woman that became a therapist after leaving the cult). The reason I suggest doing this before you start seeing a therapist is because it can definitely save you a lot of time (and a therapist's time can be costly) because you'll be going in with a better understanding of how you've been affected and what you want to work on the most, and you'll be better able to articulate it to the therapist. Most therapists won't have much, if any, experience with cult victims, so you want to educate yourself so that you can educate them most efficiently. If you're already read up and have a strong understanding of how social pressure, emotional manipulation, and propaganda were used to control you, then you're on good footing to start working with a therapist that might not be as familiar with cult control mechanisms.
My next piece of advice is to make sure you find a therapist that you mesh well with. Any good therapist will tell you from the outset that they want you to feel free to move on and work with someone else if you don't feel it's a good match. Some might be a little resistant to your characterization of JWs as a cult due to the great care the cult has taken to maintain a good image to the world - be prepared for that. They'll probably come around after some discussion about why you categorize the JWs as a cult, but you'll need to be prepared to articulate it (which is another reason some self education is useful). If they put up too much of a fight (I haven't encountered this, but I've heard a few tales of therapists, especially religious ones, that are reluctant to accept that damage was done by the cult) then you move on. It's just like hiring someone for any job - they might be a great candidate but if they don't fit in the company culture or if personalities clash, they won't be as effective.
Lastly, you should know that 95% of the work of therapy takes place outside of the therapist's office. You're going to need to be ready to work on things yourself, and don't expect it to be super easy. It'll take work and commitment. Don't get discouraged if just talking to someone an hour a week doesn't lead to some major breakthrough. They'll help you with strategies to use, but the real benefit comes from going out into the world and trying them and learning from experience.
I wish you the best of luck in your cult recovery!
