Your feelings are normal. Little things help us to get going with our lives, bur remember it will be 2 steps forward and one step back. Eventually we reach a destination. Whether or not it's a good destination is up to us. If we choose to make the rest of our lives good and happy, it will be so. If we choose to drown in our sorrow forever, it will be so. It seems to me that you have chosen the former.
Sometimes we need a good dinner (or in my case some new shoes, or clothes, or furniture, etc.). Sometimes we pamper ourselves just because we can. And should.
And yes, recovery is tiring. But surviving is not.
I hope your daughter is better. It was nice to read a victin-free post today.
