Is it too late??

Hi everyone ❤️

I want to become a doctor, from last year due to health issue I am studying from home and last year I also had 12th board exam , so , I was not able to do well in my medical entrance exam , for that I took drop this year to write medical entrance exam again and now I am fully recovered, again due to some personal issues and distubance in house i wasted 4months and I am left with only 8 months now and I am worried as *** , I am worried what if things gone like last year only , I want to study and I want to get into my dream college but it's feeling like I am not able to control anything , feeling like time is passing very quickly, whenever I sit to study want to be consistent atleast from now on , there will be someone or something to disturb me , I am tired of that , I tell my mom to not to include me in any type of events this year and don't call me whenever guests came and at the end when guests come I have to go , and my sister is pregnant and in two months the baby will come , again I have to help my mom with household things and all , I don't know what to do , I told her so many times to not disturb me but I do understand she is alone and she can't manage everything and there's no one to help her except me , but what about me , now I only have 8 months , I am worried weather i can make it or not , what's the use of me taking drop ?? If I was not studying, no one understands me , and I am just feeling frustrated , want to yell at everyone 😮‍💨
