Hey Lost, I know you have already gotten an answer, but I wanted to help contribute as well, due to your situation.
Yes, your symptoms may match up with HIV infection, but however, little details such as the amount of time your symptoms last and the specifics of the severity are left out. This leaves a person with not enough information, and they automatically generate an idea from the information they are given, but this idea is most likely invalid.
Also, you won't infect anyone with HIV just by being around them. STDs do come with a great amount of stigma no matter where you live, and it's important to not let that stigma control your emotions.
I suggest you read the link I post below. It might help your current situation.
