@Rory Phelan Thank you! ! I'd say I've done so much internal and external work, and the CO2 tolerance has actually reduced a lot of the anxiety as well as the mental fitness triaining, trauma-releasing, and other work that I've been doing. Neurocreative leadership skill development for learning myself and teaching it back out has all helped. I would say I don't really struggle with anxiety anymore. I hear what you're saying about visualisation, and yet I can visualise past experiences easily, but not necessarily future ones. It comes back to feeling into it, because as science has found, some people feel more, some people see more, some people hear more, and proceshypersensitiviesogically or through feelings. I am also aware through my own research that people more associated with neurodivergence and hypersensitivies, such as myself, will have these traits related to excessively amplified sensed feelings and subconcious protective urges. So therefore I get to ignite a sense of feeling good whilst in practice. However, the protective mechanisms that inspire discomfort going into automated compulsive responses to breathe, whether slowly or fast, is still so, so strong! This is where it's fascinating to look into. So I hear what you're saying about visualisation, yet transferring that to a sensed feeling, yet the feelings overtake more. It's fascinating and I haven't worked out yet how to relax in the face of such deeply strong urges that come up to breathe. If there are any other known recommendations to tap into the nervous system, I use tapping (eft), tension/release, and relaxation wherever I can. The breath hold time does go up, but the anxious feeling to relax while feeling discomfort remains existentially quick to come on.
