You are a kind and warm human being.
You may find your worth is some unexpected way.

If there is something you did as a teen that you enjoyed do it again.
If there is something you did with the kids that all enjoyed do it again.

Try things you've never done before just for the heck of it.

Give yourself the opportunity to be happy. It doesn't mean it will happen every time. Sitting, convincing yourself you not good at anything does nothing but convince yourself you are good at nothing.

I want you to be happy
I want you to feel good about yourself
But I can't do it without your help.
