I don't know if this is common knowledge - you can take "intermittent" FMLA. That way, you can take FMLA in bits and pieces as needed. It can help stretch out your FMLA, especially if you are concerned about using it up too soon. There's no time limit as long as you don't go over your 12 weeks per year (keep track of your hours until they add up to 12 weeks). I found it helped me cope with everything when I could escape into the work world and focus my mind on something else for a bit.

So sorry for what you are going through, big HUGS, tender wishes.
