Why do I feel so empty sometimes?

there r a few things u should do. i think one thing is find something u r really interested in, like chess or something and keep up with it. i also think it would be good to participate in a lot of afterschool activities. keep busy. Also, think about why u have a low self-esteem. Why? think about it and do something about it. U said u feel like being shy, and as much as u want to be, dont. If u still r having problems talk to ur family. ur parents. dont hold anything back. be as direct as possible when speaking to them. i would also recommend that u hang out with ur friends more, especially when ur feeling like this. Keep ur life moving, dont sit around a lot. i think all this will help and hope that its enough.
