When no one understands where I am coming from or things don't go well, I rely on myself to feel better. Believe it or not going for walks in parks that are filled with trees and shrubs of all kinds or just being in nature helps. I have an excuse too, taking my dog, another Bailey, out for his walks.
My pets keep me happy too. They are pretty funny and each has their own personality (1 dog, 2 cats).
I do not have depression ( at least for now) but I feel for those who do. One daughter of mine does suffer with anxiety and medicates to help with it. She says her music helps her too (guitar).
Sometimes I think that being busy would help people with depression or anxiety, because I think the actions and thinking requiring being busy would help you forget the problems. Just my theory.
The only true wisdom is in knowing you know nothing.
