Should I sell my soul?

I have had enough of this, I am done with studies and cannot take it anymore. I actually lost my mind and I am already suffering so much there is no guarantee that an afterlife actually exists so we don't have any clarity about hell/heaven. So, why don't I maximise my happiness on Earth and die young rather than live a long unhappy life. I was considering this from months now but I am sure now I want to sell my soul for educational success if I don't do well in JEE/Boards. My life is already hell, I won't even attend college and forced to beg on the streets as I am not talented at all. So if selling my soul can fix this why not? I have asked God multiple times for good but I never recieved it, always betrayal and horrible people from one's I trusted the most. My marks and marksheet will be there forever. After 200 years, that piece of paper will be proudly raised on my house's wall saying 99% if selling my soul could guarantee that why shouldn't I? My parents clearly care more about my grades than me. I wouldn't be here forever at best I live for 70-80 years healthily, but I do something unholy in academics after selling my soul it's worth it.

So, does anyone here into witchcraft/voodoo/satanism guide me through this.

Will I also regret this selfish and short-sighted decision? At this point this exam is clearly more important to me than my mental health if I mess it up it's already not going to recover till the end of my lifetime. So, I don't know man.

Or someone please insult me so that my messed up mind gets back on track.
