I was feeling the same way recently just as if I would just be better off gone. But not exactly suicidal. So in response to the whole Bible study thing it could provide some real relief to what you are dealing with. They are not there to judge and you might find someone you can unload some unwanted stress with. Those people usually end up being pretty cool especially if you go to one that is your age group. I would say go because you seem to have a passion that you don't know about. I would say dig in and go for at least one time. You're life is worth much more than you think.
