So fucked up and still can't do shi

I js wasted the two most important years of my academic life and got compartment in phy. I studied in jee oriented coaching throughout and scored 52%ile. I really really wanna fix all this but I js can't happen to stop myself from procrastinating. I had to take drop kyuki abbi tak compartment ke results aaye nahi h and my parents forced this decision onto me again. I really think I have adhd and everyday I have to go through this guilt trip of not doing anything but I cant ask my parents to help me diagnose it. This is my drop year and I haven't started studying till now I js want to end in a decent engineering college. Please suggest me how can I get through this.
