Observe how other people deal with theirs. What do they say? How do they act? What seems to work for them and what seems to not? It is possible you may garner something helpful from what you see others do to deal positively or badly with emotions.

Communication. I'm pretty sure communication is a big part of coping with emotions. The ability to talk about what is on our mind with another is a huge way of letting it out, letting it go, sharing, or whatever else you desire. Just like the inability to share can be stifling and make the emotion feel that much stronger. Keeping it bottled up on purpose will do the same.
