Liz33 (and others), I would still be married if it wasn't for depression. My ex wife got a dose of it from menopause. No amount of begging could get her to seek help came, and I am happy that you found some, an outlet and some good people here to lean on. The support I just read was heartwarming and genuine, a great combination.
Continue your journey with a clear head and when dark moments come up, shut them out or contact some good friends until it goes away.
Someone once said that the happiest people are often sad inside, but knowing yourself and dealing with it is a good way to move past those feelings.
I wish you nothing but success and glad to know that you are trying, that's more than my ex wife did.
