Losing our home

My name is Elsha, I am a single mom of a special needs son. I’m trying to save our mortgage. I was a US Forest Service employee of good record for 20 years and was terminated after requesting family medical leave to care for my son. My home foreclosure is on hold if I can clear three payments of $1050 in a row. ***My first payment is due tomorrow*** and I’m panicking. Medicaid told me if I lose my home they will take my boy (foster care). He’s ten years old. WTH? My mortgage company will not wait and I’m already out of funds for food and his pull-ups, etc. Im working a new job around my son’s treatment schedule tho it is scattered and my paycheck won’t be here for another 2 weeks! This is awkward for me. I have set up a go fund me account for other people in need, just not for me. Please know, I am so grateful for any help, and every bit will help us get a step further. Thank you.
