i haven’t felt anything like this personally. but i feel Allah is testing you. what is Dua. it’s what you ask from Allah. which means you have faith in him and trust him!!! but how strong is your faith, believe and trust in him??? maybe that is the test Allah is putting you through. so be strong and keep you believe, faith, trust in Allah stronger and pray harder. Inshallah all will be well as Allah knows and does the best and he is the best planer.
