Considering switching therapists and getting reevaluated

I have been seeing a therapist for nearly a year, mainly for my anxiety, but also for my depression. This worked very well for numerous issues I have until now. I experience periods of racing thoughts, excessive energy to the point that I have to be constantly active for hours on end, distractibility, and irritability. My therapist and people around me seem to think it is anxiety; to me, it is obvious it's not.

So my therapist is only recommending techniques to manage anxiety for those periods of overactivity. However, they work poorly. The only way she has seemed to help with that is by helping me get to sleep more easily. My sleep has generally become more regular, and for over a month, I have not had a period of overactivity until recently, when I had difficulty falling asleep for a couple nights. I am suspecting this is why my depression is getting worse after becoming manageable for a few months; this whole situation is making me feel hopeless.

Because of that, I want to find a new therapist, but I also suspect I was misdiagnosed. I am considering getting evaluated by a psychologist, since the last psychiatrist I went to evaluated me in a checklist kind of way, and I have heard that the evaluations of psychologists are generally more comprehensive than the evaluations of psychiatrists. I am thinking I should do that so that my new therapist can actually address my issues.

I now want to continue with the same therapist I have been seeing, since she finally understands what I am feeling when I am having periods of racing thoughts. While she has not given any label to it, she ruled out anxiety when I told her I actually worry less when I'm having racing thoughts, and she ruled out getting frustrated at other people. Based on how my racing thoughts tend to go off tangents, she has now suggested some strategies that I actually think may work and I am willing to try.
