The challenge is to just let the emotions come and go, and stay open to life. Instead of hyperfocusing on the painful part, focus on the good parts (your talents, family, friends, etc). Think of your emotional experiences as a river. Rivers take the path of least resistance. They hit a lot of rocks. But they keep moving on. They're not afraid of going over waterfalls. That's the spectacular part, but also potentially the most painful part. The river just keeps going. It doesn't stick to that painful rock and say "Man, look at this painful rock. Why is it happening? I need to never run into a rock again. I'm going to stay in this eddy and not go any further". Or "Maybe I need to lug this rock around so it can't get in my way." Rivers run into rocks but then just keep going.
You're going to have emotions. Don't hide from them or try to protect yourself from them. Just experience them, and then MOVE ON! How? Live in the moment, and don't over-analyze past issues/problems/people/
Now get out there and LIVE LARGELY!!!
