Hi. Humans are social animals and it seems your mother feels lonely now. As her age is also more she needs care and support. Her social engagement needs to increase especially as she lives alone. Having said that she needs to be evaluated for depression and physical illnesses that may lead to such increase in irritability. Please seek a psychiatrist help for her assessment and management. You can also discuss your helplessness and some management plan can be worked upon according to your family circumstances.

Hi  as caring daughter,  I can understand  the problem you face right now. There  are lot of things and suggestions which could make your mom feel good about herself and also to keep her engaged.  Do consult a counsellor in your city and give your mom the feeling of free bird back to her life.

hi, your mother must be feeling lonely after you've gotten married. ask her to improve her diet and go on a walk everyday. ask her to meet people and eventually her anger may reduce. you could also suggest her to drink water sip by sip every time she gets angry. she needs to make conscious efforts in reducing her anger. at the same time you need to comfort her and let her know that you are always there for her. she'll be fine.
