Parent HELP! Dont know what to do?

when you were a kid, she was there for you. you might have not been given a lot of care but she didnt bail out on you. Now, she needs to be looked after since she is old and dependant on you for her needs. Money, dont keep at home. keep the fridge filled and if talking isnt helping much, dont lose your cool. Her old age has made her actions childish and it will continue till her death bed. Avoid arguments and shouting but DONT givein to her medicinal drug addictions.
