Gigs are a confusing place to be when you experience any form of dissociation. For me, there are two likely outcomes. Sometimes I feel the barriers between me and everything else reduce, so I feel closer to seeing the world as a typical person does. But sometimes I instead feel more aware of the dissonance between what I’m perceiving and what I’m experiencing, and so I notice those barriers more acutely.
For people in the UK, there are two ways to go about investigating dissociation (using that as the catch-all term for everything on the dissociative symptom spectrum).
The first option to to straight-out ask your GP, if you have an alright relationship with them. As the majority of GP’s won’t be knowledgeable about dissociation, that will probably involve bringing some information about it to the appointment. It would also be best to specifically asking for a referral to the Clinic for Dissociative Studies, rather than a local psychologist.
If you’re not sure how your GP will respond, or want extra support in the decision beforehand, then another option is to contact the Pottergate Centre, a dissociation-focused organisation with an office in Norwich, UK. They have an online contact option, where you can get two dissociation screening tests from them, and send the tests back to them to be analysed, all for free. You can then take the results, and their analysis, to your GP- they will also include extra information about dissociation with the results.
