No Reason

I have a wonderful loving husband who tries to understand me and puts up with my large variety of moods.

I have two new adorable kittens who already seem to love us.

I'm starting my job in a couple of weeks.

Our move halfway across the country has been generally successful.

I have a nice apartment that we are quickly getting together.

My parents and my in-laws are helping us through this financially difficult month until my first pay check.

I am loved, blessed, and very lucky.

So there is absolutely no reason for me to feel this way. I just feel so empty. The feeling comes back anytime I stop doing something. I have this constant urge behind my eyes to cry. I don't want to do anything but lay in bed. I can't even find simple joy in playing with the kittens.

What is wrong with me? Why is it so hard for me to be happy?
