Re: Freaking out please help
It's normal to be scared before getting tested, but you just have to literally force yourself to go get tested, because only two things could happen. You will either get a negative result and can live without fear again (so why drag this out longer?), or on the chance you get a positive result, yes it will be difficult at first, but you can get treated and be as strong as you can and deal with it, but at least you don't have to be afraid anymore.
I think it's more likely you will test negative, since you had only one encounter.
Please just go get the test, and if the results are not negative, come post here, and we will help you. But realize they are more likely to be negative. Peacefull.
