Advice Needed !!

Hi Everyone!

Going through a tough phase of life. Been working in Tcs for the last 3.8 years. Growth was good here compared to others. Was employed at 3.36 as a fresher and the current ctc is of around 10 and received the promotion to c2 too. My mother got cancer around 3 years back in 2022. Her chemotherapy has been going for the last 3 years. The doctor gave her 5 years after it was diagnosed and she's facing so many issues that I don't dare wish it on anyone. I have taken a wfo exception frm this month ( went to the office first in 2024). I feel like I am earning too low and need to improve. But the issue is Tcs insurance covers the treatment cost to some extent. I still have to pay like 7-8 lacs per year but around 22 lacs is covered by insurance. I have doubts whether I should change the firm or not. Whether I'll get Insurance for a pre-existing disease of a parent or not. This is just one thing. I am not able to study, can't even forcefully do that. I also have too many health issues like ra, tmj. The feeling of not being able to do anything is eating me. My main concern is money but I am stuck and not able to do anything. Any advice, suggestions are welcome !
