My worst nightmare :(

[dancer937]

(9/30/13) 66 days ago I preformed oral sex on my on boyfriend for the first time. For this encounter we did not use protection. 3 days Prior I noticed scabs on my scalp and in my ears. I was using a shampoo that contained sodium lauryl sulfate and sodium laureth sulfate. Of course i looked on the internet and the result was seborrheic dermatitis. Immediately changed to head and shoulders. Fews days later  i noticed a ball on the back of my neck. Again I web searched it and resluts were swollen lymph nodes. During my research I saw that theses are symptoms of hiv so I was EXTREMELY overwhelmed. At the time I had loads for homework and mid-terms for college. I also was making uniforms, posters for work and had a financial problem and my dog was sick and I was scared she wasn't going to make it. I was SOOOOOO stressed out, because of everything I had to do and me thinking all day and all night that I could be hiv +. I lost days of sleep and I would find myself crying for EVERYTHING!!!!!!  I went to the doctor on 10/25/13 ( 3week after) for a regular physical and I had blood work done everything was good. I did have a UTI. They prescribed me with cerfuroxime.  As the days went by and i wasn't under anymore stress, my scabs went away and so did my swollen lymph node. Until a week ago I had my final research papers due for four classes on the same day. Again I'm starting to stress over finals and getting uniforms for work. My scabs came back and so did my swollen lymph node but now I have another one behind my ear. My have mucous in my throat and its hard to swallow and my mouth is super dry and has a weird taste.  When I'm able to cough it up I has little black things in it. Yesterday when I woke up I had a 1 red patch with 3 little bitty yellow pimples on the edge of my bottom lip. I have no idea whats wrong with me & its freaking me out. I'm perfectly healthy I'm 20 only thing is I'm overweight but my job has my dancing for about two hours every other day.  Because of the homework I sit on a chair for about 10 hrs or even more. So my lower/upper back hurts on a daily bases and I'm on a computer most of the time as well so my eyes are suffering.  

I lost my virginity to him  (w/condom).  And as well as oral (only once) with him. He has had previous relations.

Could my symptoms be because of:
Stress
Dehydration
HIV +
Please HELP me!!! I'm in need of some expert advice!  What should I do?
