Recently I found out my younger sister was self harming. We were worried about this before and hid all sharp objects. Today we found out she used a blade from an old pencil sharpener that we gave her when she went to take the SAT. On top of that we found out she shared the blade with her friend who also self harms and used it when she gave it back to the next day. Her friend recently lost her virginity to a guy she was casually seeing and even had a pregnancy scare. You can see why we are concerned. There are so many scary blood borne pathogens out ther and we are worried she is danger of having caught something. I know there is HIV testing at the clinics, but is there any test that check for all blood transmitted pathogens? If not, which tests do you suggest she gets? She is already seeing a therapist and we are now keeping a vigilant eye on her, but we need peace in mind in knowing she hasn t contracted something.
