Everyone has problems, and everyone has bad days. Everyone needs someone to listen or give advice, but finding someone who cares and won't share your secrets can be difficult. Luckily, there are some sites and apps that were made just to give people the chance to post their feelings.
Ventnation: This site lets you post anonymously or with a login and comment or give advice to others. Easy to use!
Somewhere to Write: Although there are some ads along the border, this is a pretty standard website where you can anonymously post whatever's on your mind and comment on others' thoughts.
Confide: This site is very basic; you just add a comment at the bottom and it sits with everyone else's. However, "You can't register or sign in, you can't connect to Facebook or Twitter, you can't directly comment or like anything that others say, you can't post more than once per session.
The reason you can only post once per session is to help you think about what you want to share. Get to the core of the idea, express it concisely, and others may identify with a similar situation."
Hope these are helpful! Comment any other cool sites you know of!
