Well, at some point I used to blame people mostly for been depressed. Mostly because I came from a background where you learned to swallow up any shitty experience and move on. Since I could do it, I expected others to do same.

But I learned early enough that we all have different emotional strength and I should expect everyone to be as strong as I am. It's important that we try to help others out of their own depressed state.

One advantage of offering a helping hand is that there's a certain joy one gets from helping others. You feel important and have some sense of purpose because you actually help someone recover. That can help your own depression.
