Hi, I'm another with absolutley no experience there but hugs to you.
Is there anyway you could give yourself a break to kinda re-group like a sleepover at nan's house? That is of course if Nan is near by. My sis has been doing this with her 3 year old every now and then so they get a little rest and only have to tend to the 1yo.

won't help your problem but will help your sleep for a day.
