I've been in situations where I felt awful and wanted to cancel but my mum always says I'm fine and I am most the time! I think when we cancel plans for it it makes our fear WORSE. Like we just give in and let it have its way. Not gonna lie, I do it a lot (hey I'm still an emet). I'm doing counseling now (exposure therapy to get over the Emetophobia) and I haven't really connected with mine but hey trying can't hurt. Best thing that has helped me is family (or friends) that reassure me that I will be just fine if I just do it. Think about how much you are missing because of it!
