Hey there - are you alright? Must be hard to deal with shitload of problems, all at once. Been there, it is really stressful.
I did created a funding page to feed some stray kittens once, and this is how I wrote the copy:
"I have been feeding the stray cats on my faculty ground using my own money for the past 3 years. Unfortunately my contract ended February last year and while I manage to continue feeding them by skimping on my own meals, I am running out of money and down to the last cat food stock (enough for 3-4 days). I survive on a bag of rice right now and am working really hard to find money, but I need help. Please, I don't mind being hungry but there are kittens, they need food. Please don't let them be hungry, please help me."
I think the best way to write the Go Fund Me page is just being honest - this is the kind of page where showing your desperation and stress is encouraged after all. But you have to clear and touch the high points so that your story will not drag. Be succinct and clear about why you need the fund.
If you think I can help you, lets chat. Stay strong friend - Nadia.
