So much uselessness..?

Don't EVER feel like you don't have a purpose in life. Everyone does. And, maybe you haven't found your yet. I think that you have the answer already as to why you feel this way. Try to simply say one word to someone, Hi. Say hi to someone you think you have the potential to be close too. Leave it at that. Start a conversation with someone. Just remember that, no matter what happens, god will be on your side. Don't say that you'd be happy to die. Think about all the people who care about you that would be hurt to see you like this. Just be yourself, and ignore those snobby people who make themselves feel better by picking on others.
