crossword, bloody crossword

I have always liked to give blood for Valentine's Day.
This year, I have had to abstain.
The rash on my arms has returned. That, in and of itself, is not the reason I cannot give.
No.
As the nurse told me the last time I tried to give, there has to be a large enough rash-free zone for the placement of the bandage after the blood has been drawn.
I have no such area near the crook of my elbow, on either arm.
Drats.
But I do have this cool puzzle to solve!
I thought I would share it with you, dear reader.
Happy Valentine's Day!
