[suzzane]

...and introvert girl and? never had much freinds.Actually people get bored with me and no one really comes and talks to me.I feel uncomfortable in their company and they also feel bored and uncomfortable in my company.If i am sitting with 2 or 3 persons i may talk a little but no one really talks to me when i'm alone and especially boys.people say that i talk less but i feel that even when i speak its always nonsense.And even my freinds say that u dont know how to speak...what should i do its very serious...HELP
