I'm losing my mind. *rant*

Tonight I was gonna leave . Meet up with a guy to have sex although I'm 8 months pregnant , I wasn't thinking right. A bad habit I had before I got pregnant (sleeping with strangers) came back to haunt me. I'm 17 I turn 18 next next month but social security workers are on my ass , "don't do it again or your son will be taken away" they said I thought I was listening but it tonight I didn't care. Didn't care about the consequences at all just to go fuck someone. We end up not doing anything at all becuase like a fucking cop my grandma followed me around . Why? Cause she cares. Idont get it , didn't wanna get caught so I went home . Now I'm crying hysterically WHY AM I SUCH A BAD PERSON WHY DO I DO THIS??? I don't know honestly think I'm losing my mind
