Feeling terrible.

I have just 'lost it' with my lovely DH. I shouted like a harridan and a fish wife. He had come in from the garden this evening after putting out the bins and placing food out for the hedgehogs. There was a great scuff of wet mud by the computer on the carpet and wet leaves hanging off the soles of his shoes. Bless him he is so good, he even went 'slowly' up the stairs like a naughty boy and refused to say good night. I know we will be OK by tomorrow but lately I have been very very snappy with him. He is 74 seeming 'older' than even a year ago. He did have that awful cardiac arrest followed by pneumonia 2 years ago and has recovered very well. Doctors say he is in full health, he also was diagnosed with prostate cancer for which he had radiotherapy before Christmas. I think it has taken it's toll. He seems to moan about aches and pains every time he speaks. He answers any question with a complaint about his back, knee, neck etc. I adore the man and mostly we are very happy but I hate myself turning into this nagging, snappy female.
