Waiting for diagnosis appointment - Initial assessment indicates autism and very high masking. Life flashing before eyes. Any advice?

Tell your assessors that you mask a lot. Do not expect them to divine it from just observing. The paper, 'Self-reported camouflaging behaviours used by autistic adults during everyday social interactions', found here:  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8814950/, might help you categorise and describe your masking behaviours.
