Constant Anxiety

ok ive had numerous testing and me (as well as all of my partners) were found to be HIV negative. But i find that when i get the depressed at the thought of it my stomach aches and my bowel. But the only person i have ha dunprotected sex with just tested hiv negative and the last time slept with them was  over three months ago. ever since i was 12 i would get very nervous and fearful about the hiv/aids virus but now i dont know if  something is wrong with me or if its just my mind , some of the symptoms  im referring too are

my stomcah acting up wverytime i have spicy, or lacctose foods (milk, hot wings etc.)
- this si somthing that affects my whole family so its not just me

a small rash like thing atop of my knucle, that comes and goes, i first got it in 2007 after moving into a dorm where a roomate of mines had a similar yet larger rash on his leg

reccently i developed somehwat of a cough accompanied by mucus in my throat it came in with my allergies which developed shortley after i stopped riding a bus where the bus driver smoked everyday on the ride to and from school
- i am unaware if its the second han smoke that is responsible for this or not (i have been around that second had smoke for close to 8 months before i stopped riding the bus. but i mentioned it because my moms a nurse and she told me it was due to teh fact that the pollon in the south in stronger and is the cause of my cough

i honestly dont know whats wrong with me, my doctor says i have nothing serious to worry about but anxiety and depression is constanly eating away at me. are these sytoms just the every day things a college student goes through or is it deeper than that. I need so answers so can someone please help me?
