what do you do

When your baby just won't stop crying?
I get really irritable (best word I can think of?)
And I set her down to cry because I cannot handle it sometimes- so I set her down and go into another room. Like.
When nothing consoles her and I know for sure nothing is actually wrong (we go to her dr for everything and I know she's fine).
But when I walk away she does this cry that takes her breath away and makes her puke.
I know she's too young to console herself yet (3m).
But it really messes with me mentally especially when I can still hear her.
