help with mortgage

the reason I am asking for help is because I am currently going through a divorce, I filed in July. My ex has not paid any child support at all so my income is the only income in the house right now.I am a preschool teacher and only work part time because 1 of my children has a disability which requires dr appts and therapies. He was the bread winner in the relationship and took everything when he left.  Technically I am 2.5 month behind on the mortgage because I've just been doing the best I can. I am only asking for 1 month of help to get me caught up as much as possible. Any  help would be appreciated, I usually dont ask for help but I have already reached out to local companies/church with no luck. Thank you again and God Bless.
