Okay, so you are positive, unfortunately. Needed to clarify, because not everyone necessarily is due to the issues with the blood tests.
You need to backup and not get so worried about what you've read and other people's advice on here. The first outbreak is the worst by far, after which recurrences are pretty mild for most people. The first year is worse in terms of recurrences, shedding and thus infectiousness, but things should ease up afterwards.
Each person is different, so disregard their advice regarding triggers. You won't know yours until you find out for yourself. You may not even have any obvious triggers, like me. What's for sure is that one person's triggers may not be another person's triggers and probably aren't. Your triggers may also change as you adjust to having the virus.
Best advice was from the sexual health doctor I saw. He said there was no need to change anything in my diet or lifestyle unless I observed a pattern, so I didn't. I still eat chocolate, nuts, drink caffeine, alcohol, stay up/out late, exercise, been very stressed, etc. All things you're supposedly meant to avoid. I did decide to eat even healthier and take vitamins, however, plus cut out unhealthy habits, but I didn't change anything else and discovered that I didn't need to. Regarding partying it up and drinking alcohol, I restarted slowly, only because alcohol is a known immunosuppressant. After a few months I was back to my normal nights out.
Fyi, I do not take any meds or lysine (lysine is not sufficiently proven to do much for herpes, incidentally, and definitely does not reduce transmission, so is no longer prescribed by leading HSV experts, who favour the meds instead). I am single, so don't need to be on daily suppressive therapy to reduce transmission and never took the meds on a regular basis as a result. I treat recurrences with OTC acyclovir cream only. I did take the oral meds for a week and two weeks a couple of times without any side effects. The meds are very well tolerated by most people.
So, bottom line is that, yes, it's stressful to be diagnosed with this, but for most people it's not so bad and things should ease up over time. What you see and read online are often worst case scenarios. People tend not to post online when everything is going well, usually only when they're not, so bear that in mind and stay grounded.
