What is a disadvantage of writing your thoughts l?

If however someone found out about what you wrote, they might spread it to others and even say that you're dramatic (talking about depression and stuff) but I'd say that we should just keep out feeling to our self so that we have nothing to loose ... but however, I'd also say that that's kind of unhealthy to keep burden in your heart ..., so at least tell it to a friend whom you can trust, family, teacher etc ...
