I've had enough of work; don't want to be here anymore

I have worked in retail for 14 years. I'm currently a manager of a small jewelry store and I just don't want to be here anymore. I've worked part time and full time for 10 years here and I'm so over customer service. I'm slipping. I'm on the computer more than not, I have no enthusiasm for the product. I just don't care anymore. I don't want to work retail anymore. I just don't know what to look for.

It's going to be a long day...

I'm so tired and I'm by myself at work today. I already have a headache. I just want to go home and sit with the doggie.
