If life were really a bed of roses we wouldn't be diagnosed with a mental illness. Many of us go through periods where the frustration of our illness causes us to lash out. At those times we are likely to hurt those around us. Then when we realize what has happened the guilt invades.
Thank you for being strong enough to acknowledge your illness got the better of you. I wasn't on the receiving end so can't speak for others. However, I don't hold your illness against you.
