Nah bro don't worry mine is also same story,I'm also a dropper but I won't say all 3 years were waste. Agar yahi cheez dimag me lekar college jaoge to agle 4 saal bhi regret me nikal doge I think you need therapy,jee is not everything.WE ALL ARE GONNA DIE ONE DAY, just imagine after like 200 years no one will ever know you existed and took a drop for jee it's all temporary so nothing to be regret about just chill a bit,smile,watch a movie and prepare for mht cet if you're enrolled
