Please Help: Bad Living Situation

Hello, I’m going to start off by saying that I wouldn’t be making this unless I absolutely needed the help.

I’m in another financial predicament. I broke up with my abusive bf and he moved out making me the only person to pay for a 3 bedroom apartment. Even working 40 hours a week and spending money on only bills I still am going to be minimum of $200-400 short. My lease ends in July, which means I have 4 months I need to get through. If anyone can spare anything that would be the biggest help in the world, I’m sorry to ask but I don’t know what else to do at this point.
