Single mom disconnection warning

With Covid-19, we are all struggling to get by.  I have been keeping my head barely above water, but I cannot afford to stay at my current living situation. I was on a payment plan for my electric bill but it ended unexpectedly due to the weather change and now they want me to pay 676.08 cents or else I’ll get disconnected. I talked to Evergy and they pushed it to June 22nd but it would be added to my next bill instead. This is more than my rent and I am trying my best to keep my head above water and it feels impossible. 
Thank you for everyone who has been helping me. I really appreciate everything.
