trapped in bedroom

Ugh this is bullshit but my fuckn door knob has broke I live in an old ass house.  The door isn't locked just shut and the latch won't turn when I turn the door knob. This happened earlier I had to climb out the window to fix it but it is 445 am and I'm thirsty as fuck and just woke up to find out I'm stuck in here and my bf is sleeping so hard he won't wake up. Fuck my life...
