I hope things will get brighter for you today. I think it happens to all of us at some point some days the bottom seems to drop out of everything. I have shed many a tear in my furkid's fur and it sure was a comfort. We are your friends and we understand you have lots on your mind. I hope your dad gets to feeling better soon. Chronic pain is very hard to live with and sometimes medication can give you some terrible mood swings.
Remember that your Simba girl loves ya, your parent's love you, and we do to.
