PD -
You are NOT a wuss! Tears can be a very healing and cathartic thing sometimes.
I lost my dear kitty in May and my dear dog in September. Kitty died in my arms and doggy was 16 and failing fast. I had to make the decision to let her go. I know it's so very difficult.
My mom is facing a health crisis right now (lung cancer and a very, very tough recovery from open heart surgery.) I'm not much of a crier, either. Seems my MS took away some of my emotions a few years back.
But trust me when I say I've had a couple of good old melt downs in the past week or so.
Feel free to vent any time you need to. Please know that you are not alone in your pain and stress. I will be praying for you, your dad and your dear fur-baby.
