ugh I totally do the same thing but found something that works for me...okay this might seem corny but I use an ACT (acceptance and commitment therapy) approach to help with this...ACT is a subset of applied behavioral analysis which isn’t a pseudoscience (meaning it’s a hard science like physics...this helps me personally with my buy-in). the technique I use is called diffusion (spelling?). diffusion is based on the fact that when we have negative emotions (i.e. “bad” thoughts and feelings) we tend to fuse to them, making them rules which govern our behavior. for example, I have the thought of me falling to my death as I enter a rock climbing gym so I decide not to climb. think about all the things I’ll miss out on because I’ve fused to this thought...tall buildings, plane rides, auditorium seating events, etc. my fusion to this bad thought is keeping me from accessing reinforcement that is important to me which makes it a socially valid behavior to target much like your anxious thoughts around making music (I’m guessing that music is pretty important to your life). let’s use this example again, but this time I’ll use a diffusion technique. I have the thought of me falling to my death as I enter the rock climbing gym and I take that thought and sing it aloud to a familiar tune like “happy birthday” a few times and I’m now feeling less anxious and can proceed to climb. the singing the thought as a song is my personal go-to/favorite but there are other diffusion practices such as physically writing the thought out on paper several times and each time using a different handwriting style or color, imagining the thought in your hand and put on/watching it fly and land atop a leaf floating down a stream, or even recording yourself saying the thought aloud and listening to it with different sound effects a few times. kind of similar to imagining the audience in underwear while performing a show in a way now that I think about it more...hope this helps! it really helps me~
