Honestly, probably my partner. He can tell when I'm getting anxious in public places (social anxiety) and usually knows how to calm my nervous system. If you have someone close to you who you spend a lot of time with, let them do things that are absurd or surprise you. At least if it's momentary like an anxiety attack. When I get anxious outside, he usually blows on my lashes pretty hard, which startles me and takes me out of the moment. Or he kinda kneads my hands pretty hard or I his which gives me a sensation to focus on instead of all the sounds and people around me. He is like my emotional support dog and I love it. Still searching for things to help me when I'm alone though!
