I was 16 so the doctor was convinced it was Mono. The symptoms were incredibly similar...super achy, slept no less than 18 hours a day, very weak. Just saps all the life out of you.

Took me lobbying for 2 appointments for them to test for lyme because I was working grounds at a golf course at the time. Yep, I was right. Eventually got on antibiotics and couldn't go outside the rest of the summer but other than that I haven't had long term effects which I'm grateful for.
