For me, I wouldn't even share my struggles with my best friend. It's hard to explain exactly why that is, but I don't think I could do it. Some things it would be easier to tell a random stranger at a bar... maybe because they don't have any expectations of you, and you don't have to worry about a feeling of letting them down, or disappointing them or whatever.

Having to maintain a never-ending facade of success and happiness really is draining.

No doubt.
