I see where I got confused reading your submission…you left out the element that what was at your apartment, which is amazing, isn’t something you’re worried about your mother finding out or seeing, kind of like the secret side of your life. You only mention that she’s coming to pick you up, this doesn’t mean she’s even needs to see your apartment or is going to take care of you.
That was harsh, a really horrible situation. You do have a ‘your’ that should be ‘you are’ or a contraction for that. His big chunk of dialog in the middle feels too long, but that’s entirely subjective and probably more realistic for a panicked vomiting of information to get it all out there.
I’m rambling now. It’s a very intense and scary situation that sets up the tearful ending really well.
