@Selene ... its an infection. Its not the end of the world, it doesn't make you a bad person, you didn't go out and deliberately infect anyone else, nor did you try to hide it.
That makes you a good person, not a bad person.

Don't beat yourself up. Everyone has something "not perfect" about them.
There are three sides to every story - yours, mine and the truth.
