I need some advice about UCEED

I am currently in 12th started my uceed preparation in August 2024 and still not even half way through it tbh I feel like wasting my parents money on uceed coaching (I started it too late) my parents didn't even support (not even now) me at the starting of the preparation. I don't feel confident enough to appear for uceed 2025. I feel so down on life. Can't even focus on JEE right now. I'm crying while typing this... please help me on how to keep things together in this prep..
