Depends.
I'm so used to hearing everyone elses problems that I rarely talk about my own. Even if I do talk it's not about my immediate problems. Some people pry at me, and I hate that so I'll just tell them something to shut them up.
I don't keep my problems inside, I eventually tell someone, or just write it in a journal or something and mark it private.
I love to help others by being a listening ear. Sometimes I get such satisfaction out of helping someone else that I don't seem to have my own problems anymore.
