I know just where you are coming from,I know my son loves me but can get very crabby…and it hurts…remember the song “you always hurt the one you love,the one you should never hurt at all”…she loves you…she just sounds very frustrated…I know it’s hard but smile and tell her how much you appreciate the care she gives you and that you love her…My hearing is almost gone and my son gets so tired of hearing me say “what “ and gets upset….caring for me is not easy….have perseverance…she would not be there for you if she did not love you….Place all you your trust in Jesus, He will help you….Marie Andrews age 84
