I'm seeing a therapist now too.

Quick backstory: I was born in the church and decided pretty firmly at age 12 (as well as you can know anything at that age) that it wasn't for me. This was unacceptable to my parents. Long story short, I had no choice about whether to go or not. So I shut up, went through the motions, and did everything "right" until I turned 17 and left home.

Even though I was never a believer, I still struggle with the long-last ramifications of being raised in the church. I recently realized that I have a hard time trusting my own feelings (even about little things like music taste) because for so long I was told to shut up and devalue my own opinions.

Even though I stopped attending church at 17, I didn't try coffee until I was 22. I didn't touch drugs until I was 23. I even had vague fears about tea at first and thought it would make me sick. For no good reason. I was just afraid, and the church teaches you not to think, not to research, just to obey.

It still drives me crazy that my mom denies the more intrusive aspects of the church (e.g. creepy masturbation interviews). Because it didn't happen to her, she can't believe it happened to me. I went to therapy in part because I just needed someone to hear me. My regular friends just can't fully understand. And I mean, I get it, it's a lot. A lot of the religion sounds fucking crazy to the outside world (e.g., "Yeah, every few months we had to go get dunked for dead people in a tub held aloft on the backs of twelve giant concrete cows").

Anyway, this is all to say, therapy has been helpful for me and I think it might be good for you too. You're not alone. I think long-lasting effects are probably more common than not. After all, growing up, this was our world.
