I have a few takeaways from these experiences:
1. The difference for me between "succeeding in spite of" and "failing because of" was in a few areas. One, good help being available if I sought it out. Two, being able to find a few niches - academically or in extra-curriculars -- where I could excel and feel mastery. And three, having involved, concerned adults around who cared -- even if they weren't "yours" (not your family, not teachers in your major -- they're still there and they still care).
2. Other peoples' judgments about whether you are "succeeding" or "failing" are, in fact, part of the problem. That's why I put those terms in quotes. Sometimes leaving a bad situation to take care of yourself is success. Sometimes forcing yourself to look good on paper but ignoring your insides is failure. Who knows what's really going on with other people? Not me.
3. Good health care, especially good mental health care, especially good mental health care that looks at the whole body -- these are extremely important.
4. Focusing on resilience is important, but it's only half the story. The truth is, most kids who experience hardships are affected by them, often quite seriously. It's better that we as a society figure out how to reduce poverty and misery to help most kids, rather than figure out how to help a few more kids be the exception to the rule.
We need to get back more to a group mentality, rather than an individualistic rising-from-the-trash-fire mentality.
