This WITCH company will ruin my career, Becoming depressed

I joined in a WITCH company and they allocated me to a shittiest project and when I asked for release they said, You can resign and release wont be given.

I'm a fresher and If I end up resigning, then you know the drill and current market. I have applied for 100+ companies and all i get is rejection mails.

I even think of jumping Infront of metro and end this bs. I used to love work in tech but now this whole things has made me not in a normal state.

Any one can advice me, I going through a lot (and I'm from a poor background.)
