There are lots of things that don’t sound like herpes to me
I wouldn’t say that herpes lesions really involve peeling. They start as a red bump that grows into a blister or group of blisters that is almost always painful or tender. The blisters then break open and make an open ulcerated area in the lip which then makes a crust or scab and then falls off. The process, even with a true first infection, takes about 3 days to three weeks, and never last two months. The problem with reading about something vs. having experience with is can be significant.
I think stress can be related to outbreaks but I don’t believe diet can be generalized to causing outbreaks.
But you seem convinced this is herpes that you just acquired. So I hope you can clear on this at some point.
