I'm good at hiding

Hypothetical .
Little things happen in life. Bad little things. But you get over it, move on. You're bothered for a little while but eventually you accept it and be happy again. You think 'oh well, that sucks but it's okay.' but what if all those little things happen, one after the other until you've said 'oh well' one too many times and all of the little things add up to make on really big thing? Now what if that one little thing that pushes you over the edge is a really big thing that means a lot to you?
Things are blown out of proportion and you're an emotional wreck, wallowing in self pity, waiting for a confidence boost you're scared won't ever come.

But it doesn't matter, because this is all a hypothetical situation right?
