What follow-up care did you receive on discharge? Are you seeing mental healthcare providers now?

The role of the psychiatrist in hospital is not to provide therapeutic care. Their role is to make a diagnosis and stabilise you to the point you can be released. Care should not end upon discharge. You should have been referred to a psychiatrist to continue/supervise your care. Some psychiatrists will offer therapeutic services but this is usually the responsibility of therapists.

Remember too that you have your own responsibility when it comes to your mental healthcare. When you do go to a psychiatrist and/or psychologist, know that it is a working relationship. You have just as much a responsibility for a successful outcome as does the therapy provider. It takes work. I have the impression, perhaps incorrectly, that you think otherwise.
