I would like to add, you seem very ashamed of your sexuality and contracting herpes seems like it would be a physical manifestation of this encounter that causes you so much shame.
The dread and fear herpes causes for the vast majority of people is completely unwarranted. Genital herpes is no where near as dangerous as some of the other other STDs. In fact, mostly just pregnant mothers should be concerned about genital herpes.
Survey after survey show that people are more afraid of herpes than they are of gonorrhea, chlamydia, hepatitis, HPV, trichomoniasis, genital warts, pubic lice, syphilis, bacterial vaginosis, scabies and pubic lice. This is utterly ridiculous given the more negative impact these STD's can have on human health compared to herpes.
Nine of what you suggest is even remotely herpes related. You didn't contract hsv from your two min protected encounter. Stress is your only issue here.
