It has to do with the fact that I know lots of people don't like hearing others vent, I know some are okay with it but others get very uncomfortable. I've also seen people talk bad about someone who vented to them, basically calling them a negative person even if the person had a legitimate reason for venting. I don't want anyone to see me as a negative person, I don't like burdening people with my problems. I also am afraid to be seen as immature or unable to handle things myself since it can come off that way depending on the situation and who you're venting too, just makes me feel worse after venting to someone and once I tell them everything is fine after all then I feel better.
