I often go through a roller coaster of emotions when I do therapy with clients. I have a new client that is a challenge for me. When I have an appointment with him, I prep before hand- thoughts of "can I find some useful or new tool that will be helpful for this client?" (triggers worry, doubt). Right before our session, I feel some anxiety/tightness in my chest about how our session will go- thoughts of "what if this doesnt work and he thinks I am not a good therapist?" (triggers imposter syndrome). A couple times a strategy did not resonate with the client -thoughts of "what if he thinks I am useless/stupid/not helpful/terrible therapist? or another strategy that doesnt work and I dont know any others? what will i do at our next appointment? what if he doesnt want to make another appointment?" (triggers fear, lack of self confidence, negative self talk, anxiety) but one session he was very receptive and liked what we did in session. I was very suprised and felt very good afterward- thoughts of "I do know what I am doing! I am a good therapist! thank god something worked! what about this one did he like better? I can do more of this tool"  (triggered increased confidence, increased energy and enthusiasm) and this carried into my next session. I have these similar feelings at various times with other clients, particularly ones with chronic issues or that make statements of "i feel like this will never get better" as well as the positive statements of "you have helped me so much", "i tried what you said and it really helped" or "i was proud of myself for doing ___".
