Headache for one month

Hi Guys
it's my second time posting on this forum, I had possible HIV exposure (broken condom ) more than three months ago. i started to develop some of the HIV related symptoms couple of weeks after. my symptoms have not started all together. instead they happened one after each other. I have been involved with these symptoms till now which i am really confused. I had negative abtibody test after 87days and negative HIV PCR RNA after 40 days post exposure.
i still have minor headache in front and back of my head most part of the day. also i have a swollen lymph node on the left back of my head and a slight swollen lymph node on the right side of my neck. when i started to have HIV symptoms i didn't have swollen lymph nodes instead i started to have pain in my lymph node under my neck after week 11 on both sides. the pain and stiff neck lasted for 2-3 weeks.    
i confess that i didn't have a life for the past three month, been always depressed, hopeless and tired over what i have potentially done to myself.
have you guys seen a case like mine, someone with hiv with negative tests for the first three months? i don't know why i have headache for this long one month.
i was a healthy individual so i don't have suppressed immune system. do you guys think this headache and my lymph nodes could be still associated with hiv. I have seen my doctor several times and he says it's stress. but for god's sake, this is so real.
please help me
