Have you called the number again? Are you still getting their voicemail? That is so odd. I would call the mental health line again, explain the situation, and ask them to find another crisis number. You really need to talk to someone. All of the 3 times I’ve been IP the past 2 years I was admitted with the diagnosis of a mixed episode. If you are suddenly feeling very bad, and a mixed episode will make you feel that way, you’ve got to talk to a professional to see what you’re next course of action should be. Being in a mixed episode is not just hell, it is dangerous. Please do whatever you can to talk through your symptoms. Keep us updated on how you’re doing.
