I have to say that I feel I was like that for a really long time. I was always the person who others turned to to share but it was harder for me to talk and share what was going on with me. A combination of last year and a ton of family stuff was really taking its toll on me and I had no one to talk to. So, I made the decision to seek out help. My advice would be to ease the person into it; bottling things up for so is a hard habit to break. And if the person is an introvert that might make accepting the idea of talking to someone even harder.
