Hi madnessreturns, good on you for telling your manager about how you're feeling. At least it makes it clear that if you're struggling in your job it's not for lack of trying or that you don't really care about it, it's not about you it's about the depression.
And it sounds like you have a supportive boss there as well for when you are ready to return. As for getting a psych appointment well as long as you can explain to your boss the soonest they can see you is.............hopefully that will cover it??
With the time off till then though, I'd say that you can probably do with a bit of a break, considering the way you've been feeling, right??? It's feeling like you're on complete overload at the minute with trying to hold so much together.........and the longer that goes on.............
