I have been married and live in a different country than my parents. My dad is 66 years old now. Few years back, he became very silent, introvert, started avoiding socializing with other people, gave up his post-retirement job and would stay at home just lying in bed, not shaving or bathing. He would even go out for a walk. My mom has been trying a lot to help him to be engaged. She even took him to a psychiatrist who gave him allopathic medications for generalized anxiety disorder and depression. My dad took those medicines for nearly 2 years but they haven't helped much. Currently he is taking some homeopathic medicines for the same which seemed to help him somewhat. There was some improvement. They came to my place when I had my first baby, during which my dad was much better. He would do his daily activities very well and even went for a walk daily with my mom. He watched TV, read books and spoke pretty well with all of us. They left 2 months ago and since couple of weeks he has again been avoiding shaving, bathing and going out. My dad is very stubborn, he does not listen to my mom or my granny or me. My mom is still working during the day and so he just lies in bed most of the time. My younger sister's wedding is approaching in couple of months and we will be having many guests at our home for a week or so. We dont know why this happens to him on and off. Why does he gets this kind of bouts in his behaviour? My mom thinks he might be anticipating all the people coming and feeling anxious but we dont know. He does not tell us the reason. If asked, he just says "he is fine, nothing like that". She is tired of seeing him unshaven for days, she has to force him to shave and bathe. My mom feels depressed of seeing my dad in this condition. We are afraid of how he is going to behave during the wedding days. I want to help my parents but I dont know what to do. Please help me with your suggestions.
