I have discovered a potential trigger for myself with the latest saga in my life. Facebook! The root of all evil

I misinterpreted a message as meant for me and when I realized it wasn't, I feel right back to the bottomless pit of emptiness. I'm crawling back out through the rubble, at least this was a week.
I've decided to take a break from facebook and when I return, hide posts from a certain person until I feel I can handle the emotional beating and misery it puts in my heart.
