Probably depression for a long time, and finally god over it. Then she decided to write a song about her big achievement, possibly? Love is complicated, and hard to get over with. It can haunt you for the rest of your life. But some people still get over it anyways. I think that's the meaning of this song, to show people that not everything is bad, if you can't change it, then change the way you think about it! Everything can be good in it's own way, and nothing doesn't have a two-way out. Just wanted all of you out there that either dealt with a break-up or having a crush on someone that doesn't like you back? Get over it. Ever heard of the saying "There are many fish in the sea?" You will always find someone that really, truly loves you.
