Ah man, I know that feel. Had a shitty couple of days myself, recently.
Last night I watched that video of those two guys who raised a lion and then went to visit it after having to release it to the wild a year previously.
I won't spoil what happens for those who havnt seen it. But it cheered me up immensely. I think the lions name was christian?
Google it or YouTube it, should bring a smile to your face.
