What a sad paradox. You'll get over it. Grin and bear it. Don't be a wimp. No pain, no gain.
Teenagers are especially susceptible to emotional pain that is frightningly intense.
They find it difficult to think of tomorrow when today is so overwhelming. They live in the moment. They are that much more vulnerable when the next painful moment comes. The new pain sometimes compounds the old, rather than replacing it, growing into a vast, amorphous psychic pain of many interwoven sources which is difficult to unravel. In these cases, teens never quite get around to learning to cope.
