Mine also started when i was very young, my sister would get sick ALL the time, at least once a month with an sv* and she would throw up uncontrollably anywhere and everywhere, and my mum would panic over it thinking she was seriously ill. My main fear back then was being in the car or a place i couldn't escape from if she was v* which would cause a panic attack. Then it progressed to panic attacks if she ever got sick, then panic attacks if anyone else got sick, then anticipatory anxiety over the fact she 'could get sick and any moment'. Then the avoidance behaviours kicked in, i refused to ride in cars, refused to share our bedroom - slept downstairs everynight etc. But i wasn't afraid to get sick myself, i never picked anything up from my sister so it didn't cross my mind. The only time i had an sv was when i was 12 and i only v* 2 times, i didn't like it, but i wasn't panicking or anything. Then as we got older my sister grew out of her constant sickness and i became less panicky. Then one day out of the blue last year i had a panic attack in the middle of a store, felt like i was going to throw up and HAD to get out of there. That's when i started avoiding stores in case i couldn't escape fast enough if i needed to throw up. Then i started avoiding everything, not going out anywhere. Then i had constant panic attacks in my home, i hated the thought of v* in front or around anyone so barely left my room. I had constant daily nausea and felt awful. Luckily now i have pushed through some anxiety and can go out for short periods of time. It has been very difficult and i still struggle daily. But i know we can all get past this and live our lives
