I cannot add to what Rapunzel said. You have a very good handle on what is wrong and how you need to be viligant, but I suppose the depression keeps you from seeing that. Which is not to say that you are OK, but rather that you will be OK, just keep relying on the support that you have here and in life and ask for and get the help you need.

I think the real problems come for people who don't recognize that they might be slipping, or are reluctant to ask for help, until they actually are slipping and fall into a worse state.
