hey, know what your going through ,but it really is important to go get tested, don't know about where you live but i'm from the Uk and i remember that if a partner was found to have it then you would be given treatment for it anyway because its likely that you could have it. I'd suggest getting a general testing for all stds.
no one needs to know, they are not going to tell anyone that you have gone to get tested unless you tell anyone.
I know its really scary but at the end of the day, would you rather be scared about finding out about it, or scared about having it and doing nothing, which could lead to later problems. Well that was my thoughts on it anyway- i'd rather just know the answer and get it sorted than worry.
Also if you did have it, its really easily treated and you will feel so much better just knowing the truth.
Hope you are all ok though- good luck.
