Sage, sorry to hear about your cat. Early last summer, we had to put the family dog who lived with us for 13 years to sleep. This was right around the time that W was questioning her commitment to our marriage, and sometimes when I'm feeling a bit melodramatic, I look at that as the death of our marriage as well. My W moved to Washington to be with me, and didn't know anyone in the area. I was in the navy, and was getting ready to go out to sea, so I got her a puppy so she wouldn't be alone while I was gone. She was a great dog, and even though I kept telling myself "It was just a stupid dog," I still grieved. To this day, I still miss our pup.
Hopefully the cry got a lot of the negative energy out of your system. Remember way back in my sitch, when I finally broke down and completely lost it (sound familiar?), the next day was the day I fianlly began to recover my life.
I know it hurts, and I wish I knew what to say. I'm planning on drowning my sorrows in Mexican food for lunch today, I'll have some for you too.
I know God won't give me anything I can't handle. I just wish He didn't trust me so much.
