Blogging has been an interesting experience for me because I can write about what I think without having to worry about writing in a certain format (like most essays). If anyone else has thoughts about something and wants to let them out in a safe environment then I would recommend writing a blog. In a blog of your own, anything can be said without worrying what other people say. People might Criticize your writing, but since it is your blog, you control what stays on the site and what does not.
The last thing I have to say is that whether it be blogging or not, you should find something that you enjoy doing that helps you let off steam. Blogging is a good way to say what you want, but it is not always the best way to get your point across. If you like sports, join a sports team. If you like singing then start a band. Just try to find something that you can do in order to better yourself!
