There are some online services like 7cups in which people talk with strangers about their problems just to vent, allowing them to talk freely without being judged. For example, many teenagers don't want to talk to their parents because they feel they won't be taken seriously or they will be dismissed with a simple "that's because you are young". Another example could be when people don't want to worry their close ones (a thing that many depressed people do, to avoid being a burden).
