Truth is I just want to fit in and don't know how.....

when i was depressed last time, i searched net a lot to find out some help,tip... one advice was you actually don't need to be confident, just pretend you are confident... it works most of the time... pretend you fit here,these all are your friends... perhaps you can deceive yourself in thinking you fit here... and honestly aren't we like masters in deceiving ourselves... we think everything is worse when there isn't good reason to think that... all that we can do is try....
