(Sorry for my long story. If you just want to skip to the advice, you can skip the first paragraph)

I've been in a similar situation recently. I started with T1, who is so sweet and I feel comfortable telling her anything, about a year ago after a relapse. Shortly after I started with Pdoc1. I started to feel like I wasn't really progressing in therapy like you said. In addition to this, Pdoc1 did a crappy job of managing my meds so I wasn't in the best place. I expressed my concerns to Pdoc1, who didn't like T1 from the beginning, and he referred me to T2. T2 treated me like I was 5 and was just telling me stuff I already knew. Without telling Pdoc1, I went back to T1. Things got worse with Pdoc1, so T1 recommended us to Pdoc2 (who is AMAZING!!!). I finally told T1 that I didn't feel like I was progressing. Shortly after I believe, T1 started telling me directly that she did not know what to do to help me, but that she was happy to listen if it made me feel better. I again expressed these concerns with Pdoc2 once things got settled. Pdoc2 referred me to T3. I saw her once and then she told Pdoc2 that she didn't know what else to say or do for me. I then again went back to T1. I told her we got a second opinion and she was fine with it. I've been pretty transparent with her about the whole process. I think even though it hasn't been discussed directly, we both understand it is time for me to find someone else. Pdoc2 then referred me to T4 who practices EMDR (T1 only does CBT) and talked to T1 about that too and she was supportive of me trying it. She even told me to tell her if he was any good so she would have another person to refer to. Shocker, but I didn't have but 2 sessions with him. He was very set in his ways and thought he was always right so it was more of a personality conflict than anything. Pdoc2 gave us a name for T5 so hopefully we'll find someone.

I've been transparent about the whole mess with T1. She had been super supportive throughout the whole thing. I'd recommend doing the same with yours. I'd first express your concerns that you aren't progressing because like the others said, they might just not realize it. If they say they don't or you find it didn't change anything, I'd recommend seeing someone else. If you have a psychiatrist, you could ask them for a referral or straight up ask your therapist.

And honestly, I know it's hard to tell them that they are not doing a very good job, but remember this is YOUR therapy and you are paying for it! You can pretty much say whatever the heck you want. Don't settle for anything less than you deserve which are the resources you need to live the most fulfilling life you can. I spent a while waiting around to even get help in the first place and a while with Pdoc1 and I wish I had been more proactive and not been ok with care I knew wasn't helping me as much as it should. I wish you the best.
