Hi 15m here, I want to know if hypnosis can make you less shy or more brave overall?

I am clinically-certified but now years later I can see that that additional training was broadly defined and was just scratching the surface. I had my first Vet client last week and want to see more of this population that could really benefit from hypnosis. I've also dug around on the internet and have a better understanding of what Vets are dealing with. They can have sleep issues, pain issues, nervous systems are stuck in high arousal states, not to mention PTSD. There is a bunch of training out there so I thought I would post this in the community that might have so good, solid recommendations on getting more specialized in sleep, pain management, and PTSD. My scope is that I am a non-therapist, non-counselor.

I don’t have access to a professional hypnotherapist at the moment so i was wondering :are there any free recording/ videos online that worked for anyone? And if there is a way i can check how hypnotizable i am. Sorry if this is a repeated question i am new to hypnosis.
