It's the emotion at that moment which matters. Feel it. Let it go. Move on. It's a memory now. Good or bad, that's for you to decide. It differs from different perspectives.

Take a deep breath in. Let it out. Let all your 'bad' thoughts out. All the negativity, out with it. Your an amazing person. It's all in your mind. Breathe. Live. Smile. I want to see that twinkle in your eyes. Nah, not yet.... Aha! There it is! 
 Now, with this positive attitude, see all the good things in life. Look outside you window. Observe. Listen. 

Have a great day!

P.S Don't forget to smile :)
