As yungerman1 wrote, there are different type of therapy. I personally suggest “Systems Therapy”. This type of therapy is more straight to the point, and (from my experience at least), has a goal of how many sessions you will go for. Therapists with other approaches may just say to continue going until you’re ‘all better’, whenever that may be. A Systems Therapist should be able to tell you after the first or second session how many sessions it should last. Also, try to find out which approaches didn’t work for you in the past; many times it’s not necessarily the therapist who’s bad for you, rather it’s the type of therapy. So if one approach didn’t work for you, don’t go to another therapist with the same approach. One more thing, if money is the main issue, divorce may make it even more challenging. It may be obvious to some, but I would say that you should always speak to your rav before making such an important decision. If you don’t have a rav, perhaps you know a rabbi that knows you personally. The reason for speaking with a rav is that they can advise you based on the torah they have learned.
Hatzlacha!
