Try not to be too hard on yourself.

I am in the same boat.
I havent applied to a new job in 4 years... infact I havent worked for almost 4.5 years. Been a stay at home Mom. Had two children back to back.

You might not think you have skill but you do. THink of the work you have done... and apply yourself. No one is unemployable... its all about making a good impression. And you can do it.

I hope you find something that will make it easier on your stress level... and help you get that confidence back you need.

Lots of good karma your way.
