You may really want to help a friend or coworker who is struggling to keep up right now, but there are limits to what you can do. Don't beat yourself up if you can't make their world as bright as you feel it should be. Everyone goes through tough times, and this person will get through it. More than anything, they just need your support right now. You might not be able to change anything for them, but you can be their friend: and that's priceless. So just aim for that.
