I'm a failure. I have no purpose in my life.

I'm 19YO boy from india. I'm preparing for NEET (medical entrance exam) but i didn't even study for a single day bcz i don't feel like doing it. I'm a failure in everything. I don't have friends. I didn't do anything that my parents can be proud off. I cry everyday just sitting in single room. I also got addicted to Mast*rbation while just living also. I achieve zero in my 19 years of life. I wanted to just out of this body now idk🙂
