Therapy can be great. Some time ago, while still in college, I was feeling overwhelmed by it all-relationship, job, school, leaving behind the faith I'd had for 25 years...it was a bit much for me to deal with. I talked to a great therapist, who turned out to know a lot about the witnesses, so I did not have to keep explaining things like disfellowshipping to him (saved so much time!). It took me two sessions to get it off my chest, and it helped me immensely to realize that I was a normal person dealing with somewhat abnormal situations. A good therapist can help you work through your problems at your own pace, and is worth the time and money.
On the other hand, many years ago in Texas, I saw a female therapist who was just awful. She (a thoroughly white, English speaking lady) could not get it through her head that I spoke English as well as she (it being my native tongue). She kept speaking to me in Spanish, and I repeatedly had to tell her that I don't speak it very well at all, and could we switch to English, please?
If you get someone who is clueless and won't pay attention to you (like her), don't waste your time, switch to someone who is a better match to you; it may take a little time to find the right therapist, but it's so worth it. Best of luck to you with your therapy; I hope it helps you to feel better, and to find more fulfillment in your life.
