oo god I have those days too, and they can be induced by so many things that I am to sensitive in front of, I build up anger, pain and disappointment, until my emotional state is so stretched, that I need to break down, I even feel physical pain, and feel the need to cause more, like the physical would cover the mental and emotional.
I sometimes bite my lip so hard or push my nails into my fist and only something or someone outside myself can calm me down.
and you are so wright the best cure is love and respect for yourself.
I'will continue learning to love myself :)
luv you for sharing this too :P
