Skin Tear

I have fragile skin
So if it gets knocked instead of acting like normal skin it tears and rips like paper
It's bloody painful and bleeds like the very devil
I knocked myself on the door handle this morning
And it's torn so I've washed it ,dressed it and now hope it heals
Twice before I've ended up with cellulitis so that's a worry
Fingers crossed I'm not having much luck at the moment
