Welcome to PC. My heart goes out to you. Sounds like you have your hands full. I can relate to your feelings of anger, irritability, and sadness. I have dealt with them myself. Are you seeing a psychiatrist? Are you on medication? If so, have you been on it long. Some of them take a while to work. Are you seeing a therapist? That might help. Hang in there and keep posting. There are a lot of nice people on PC and may be able to be of more help than me. But I wish you the best.
