What can i do to numb emotional pain, ive just been really depressed today thinking about my dad....?

My pops ped away 8 years ago, I just turned 21. Best thing you can do is go out and keep your mind busy, find yourself a hobby, go out with friends and have fun girl; have a couple drinks and enjoy yourself, cos if you keep thinking about your pops, its only going to hurt you more, and everyone around you.
