Chastity and orgasm denial discussion

Clearly she isn’t aware that I am under my partner’s control and wear a chastity device, though I wasn’t planning to bring this up with her. I won’t get into the specifics, but I deal with anxiety issues and struggle to unwind and rest. My therapist recommended that masturbation could help me sleep when I’m stressed; it is the first time she has ever offered this suggestion to a patient, and she seems confident it will be useful for future cases as well. This made me ponder other chastsub mental states. Do you become irritable if you don’t climax? Is staying chaste such a smart move given that an orgasm can have such soothing benefits? Could being in chastity be feeding my anxiety? I know I do not want to cum; I am a much better submissive when I hold back, and there are other methods for unwinding. Still, it has me considering what steps I should take in the near future.
