Dont beat yourself up just cuz you are having bad day. We all act a lil crazy sometimes, even if we dont mean it. Just apologize and im sure it will be fine. She is your sister after all. My sis has been absolutely horrible to me over the years, and has attributed to my depression many times with her harsh words and judgements. If i can forgive her over and over again im sure yours can too. Tell her not to cry over spilled noodles. lol Sorry, just trying to make you feel better..Did it work? Hang in there and hope you get a therapist really soon. It helps to talk to people who get paid not to judge you. lol....No but seriously therapy may help so please try, and keep your chin up.
