Have ruined by life by my own.

11th: Joined a trash local coaching, no regular test and even the papers used to not get checked. Decided to leave it. Almost 11th is fully wasted 12th: Joined 12th Lakshaya jee, started great, completed all chps, then I decided to complete 11th along with 12th which resulted in my 12th being a whole godamn backlog. decided to quit JEE, I'm a hsc board student so I switched to MHTCET, but studied no shit for mhtcet, boards at the moment, and I'm on reddit, every revision feels like I'm just learning it. I guess I'm gonna fuck up my boards, as well as MHTCET.. What should I do now ? Should I take the usual drop year strategy? Have ruined my life by my own\*
