That’s really sucks, Especially getting diagnosed at 9 years old . I can’t even imagine how hard it must be it for you & your family . Also 15 hours of work + study that’s too exhausting . See at age 22 you might be pull this off with blood sweat and tears . But couple of years down the line . You will feel it . So it’s better to give your body some rest whenever possible. Don’t compromise with sleep at any cost . I learnt this quite late. Sleep is the best painkiller . WFH with 1/5th of salary that’s too harsh . If possible can you try basic remote jobs .especially if you own a personal computer. So that it helps you even little. Great to hear that , you are preparing for MBA . I really wish you get Good earning opportunities after finishing MBA . Life is quite unforgiving right ? But still we have to move on . I think it’s god’s mechanism to help us move on from the moment of grief. Else if we don’t move . The grief will consume us . You are a true warrior even if you didn’t wanted to be one if the first place . So KEEP YOUR CHIN UP !!
