I think it's a bit hard to recover from depression without outside help

Indeed it is, but the person experiencing the depression needs to do most of the work, no one can do that for them. Like you say, "the willingness to not only move on from it but to get help from others."

We have to accept reality sometimes

We should be accepting of it all the time I think, meaning that we should acknowledge and accept that what is happening is happening, that way we can add some input and influence it. Living in denial isn't going to be much of a life.
