I think you need immediate professional intervention. To become suicidal over an issue that is so insignificant and over a response that was totally predictable is very alarming. I would go inpatient to be evaluated right now. And I would take this post, because your language - that suicide seems SO REASONABLE - is very concerning. What you verbalized later - that you think that nobody would care less if you killed yourself and that OD'ing would be AWESOME - is fairly typical for your age group, but that suicide seems REASONABLE sounds very dangerous. And I would not call a volunteer-staffed hotline - I would go straight to the closest ER for evaluation by qualified professionals.
