You got an appointment with the gastroenterologist - that's great! That is a huge step in the right direction!
So no, not everyone is ignoring you. You called them and laid it on the line and they agreed to see you and gave you an appointment.
While you may not actually be planning to kill yourself Davey (thankfully!). I hope you will take Astro's words to heart. He DID get help and he just told you how he did it. Perhaps it's time to get that help? When is the last time you were in a psych ward? Things change. Different personnel get hired, it may not be what you imagine at all.
