Maybe talk to the doctor about what's going on and see what he says?

Also, you shouldn't let your pact stop you. You could make a pact to live as healthy as possible so as not to require hospitalization ever, but if suddenly you need an appendectomy, you shouldn't (and I'm assuming wouldn't) deny yourself that because of your pact. Don't treat mental illness any differently. If you need to be hospitalized, then don't hesitate.
