Hubby issues!

I'm to the point where I'm exhausted, sleep deprived, have heart burn, can't breathe, and am just generally uncomfortable....I just want a small amount of sympathy from my husband but anytime I complain or make the tiniest comment he tells me I have nothing to complain about because his job is more physical than mine and he runs around for 12 hours and blah blah blah...it's really getting old hearing it and it makes me want to punch him in the face...i know how exhausting 12 hour shifts can be i left my last job because of it....he is going to be gone fishing all weekend and I hope some space will help but ugh I'm just so sick of it...I feel like he's being so selfish and just doesn't care how I feel or how uncomfortable I am...
