My sister has been diagnosed with anxiety/panic attack/depression. Which has turned her behavior to get very annoying with people. she talks with a raised tone of voice and this make me angry and sometimes it forces me to talk back to her. she speaks rubbish that's why i get mad just to correct her. but then, she will say i wont understand her and this makes me upset. i wanna help her but can you please show me the correct way to interact with people with this disease?
