I'm HUMILIATED!!!

I live with my step dad and step brothers. My mom died last month and I'm having such a hard time coping. My dad sexually abused me and my mom is gone... I've been laying in the bed depressed because I have no one. My step dad brings my dinner to the room. I'm on my period and my step dad came into the room and said "Abby. You left a mess. Can you plz clean it up". I didn't understand until my 13 year old step brother said "She bled on the toilet seat! Disgusting!" And my step dad yelled at him saying "And when you stop pissing on the toilet seat you can complain!" Then looked at me and said "Can you plz clean the toilet off. I understand it was an accident". I'm gonna die!
