Anyone else struggle with respite care?

My MIL has hospice - so I can get respite care for 3 days every month. It should be wonderful but honestly, I've used it twice in the past 12 months and...........well, it's almost worse for me. Once she is gone, I am able to start living normally again but by day three I must adjust myself to her return. So I kind of feel worse when she returns because I had a taste of freedom. I don't know if that makes sense to anyone but I'm almost better keeping the pattern than interrupting it with freedom which is snatched away.
