Seborrheic dermatitis diagnosis after 1 year 5 months

After 1 year 5 months of unprotected sex with an individual of unknown status and a negative test at 4 months post exposure, I was diagnosed with Seborrheic dermatitis today. 4 months ago I started to experience itchiness on my face - cheek, mustache, eyelids and between my eyelids on my forehead, flakiness between my eyelids . This is something that I had not experienced in my life before this exposure. I live in the UK and the HIV test was performed at a GUM clinic here. I am now begining to doubt my results as this is getting scary.

I am married and just messed up somehow. I tried to protect my wife from this by absteining from sex for 4 months just to be clear. If this should turn out to be a false negative result, I don't know what I could do with myself. There is so much going on in my head now and it looks like I am losing my control and composure as I write. I intend to get tested shortly but what could I tell my wife and family should this turn out to positive. I don't know ..., I don't know......

so you've got seborrheic dermatitis.

you've also got a conclusively negative hiv test proving you dont have hiv.
