STDs. In need of a friend.

Hey girls, i'm just looking for someone to talk to. I'm getting tested for everything on Friday. In a way i feel like i've been overthinking and making myself feel this way. (I once tricked myself into having all of the signs for pregnancy when i wasn't). I have extreme lower back pain, pain after i've urinated but not during, and yellow discharge. 
Id like to talk to someone who won't judge my actions, but help me better myself and help talk me through this. Thanks.
