However, i too struggle with sensory overload leading to fatigue and migraines and when going out i tend to be "armed" with the Flare earplugs(in the link above), which do filter high pitched or very loud noises in the background so there is a higher chance i will be able concentrate on a conversation for a while longer than without them.;or with ear defenders and dark glasses.( Or all together sometimes) Hope that might help you if you try.x
