My mother is 77 and is starting to show her age but has not been diagnosed with any age-related conditions. I live with my parents due to a trauma I experienced at age 32 and they have been very supportive. Standing up to people is very hard for me. I am a beginning caregiver and very lucky that I have wonderful parents. My mother sometimes snaps at me and my father - for various reasons but it makes me see red. Once when she asked who I was talking to, I said something like "I am not sure why you are asking me that?" And she got mad and said that I was being touchy. Any suggestions? Thank you!!!!
