I agree, some people are good at covering it up. I'm one of them. Sometimes I wish I wasn't because I would have sought treatment much earlier if I'd allowed myself to "be" depressed. Instead I told myself and others that I was fine, just fine, until I couldn't take it anymore.
I'm sorry you're having such a tough time of this, and I'm glad you've been seeking treatment. Keep going, and know you're not alone in this.
