Since our parents are aging and we are becoming more mature and so much involved in our chores, we tend to overlook them in some situations. My mother has been a little unwell(nothing too serious) for the past 3-4 months and since college has reopened now, I feel so worried and unattentive in my class and the tasks I perform coz I am constantly thinking about her. Earlier I used to sit all by myself in my bedroom and be engaged with my phone or laptop but now I just want to spend more and more time with my parents. Whenever I see them with full attention I happen to become sad on thinking how I'd lose them and this makes me so anxious that it keeps my mind occupied more than I know. I've been feeling really sad about all this. I don't know if its normal for me to feel this way and be worried about losing them. Please help.
