On Being Super Sensitive...

Can anyone else identify? And if so, are you willing to share coping skills? I've been overly sensitive my entire life. I feel too deeply... Everything from everywhere. Most of the time I don't know what is mine and what isn't. I cry tears of joy, of sadness, of injustice, of triumph, of fear, of love... I know I would rather feel too much than nothing, but I have to believe there is a working balance... Please help!
