My dharma and detachment are clashing with each other.what can I do

I am studying to pass the judge exam in my country . My dharma has helped to push through long study sessions but it is causing me get attach tp the outcome(exam), leading to burn out, procrastination amd making me exhausted all the time.

I tried detachmen but because of it I study less and I feel like i am not doing what I need to to be doing

I am not sure how to approch it, I need my dharma as it my strenghtt through tough times but I also need my detachment as it is something that keeps me going in nornal days instead of procrastinating.
