I asked my friends, How do you be happy for someone when you are feeling sad?

And I had plenty of good answers. But this one is worth sharing here:

It’s valuable to keep Jeremiah 29:11 (NIV) in “your face” when going through  though a sad or confusing time.

“For I know the plans I have for you,” declares the LORD, “plans to prosper you and not to harm you, plans to give you hope and a future.”

God KNOWS the PLANS He has for YOU. They are GOOD plans full of HOPE and a FUTURE.

Also: KNOW there is an enemy at work attempting to create fear and doubt - wanting you to fail.
