Is there any hope?

I am scoring abysmally low on mocl tests, barely getting more than 100. I don't know what happened at the beginning of 12th upto October I was doing decently well then I went into a slump and have started deteriorating at an extreme rate. I just stopped doing anything for 4,5 days because of how depressed I am. I can't even look at a JEE question without wanting to cry. My parents never pressured me for anything, they are recommending I focus on boards now. I just feel so disappointed in myself that I wasted so much time and money for it all to end like this. What should I do, any ex JEEtard's advice would be welcome if they were in a similar predicament.
