Don't ever let anyone break your soul. You have to stand on your own two feet and fight. There are those who would give anything to see you fall, never give the them the satisfaction. Hold your head up high, put a smile on your face and stand your ground.
I literally live by this every second, of every minute, of every hour, of every day. It is good advice. It's ok to be sad about something, but you can't let it take over your life, when you let it do that it not only puts you life on hold, but it hurts other people.
