you really should forgo what she says. She may have been unappreciated, but so what. Water under the bridge... Forgive yourself, no good will come from connecting your testicles to a live car battery to make up for it. There is a VERY good chance she is just fibbin' it, making excuses for her actions. Either way, let it go.
Take care of yourself, starting now. Grow a spine and a healthy pair of cojones. Time to tell some people to go fcuk themselves. It is very liberating to do so. Time to start demanding respect you deserve.
Time to start liking yourself, which with a bit of luck will lead to a love affair with yourself. No one else can love you, until you love yourself...
