Zikr & Dua

Q: I am very sad, worried, depressed and lost. I'm doing everything to please Allah but nothing is working out in my life.

I read 125000 times ayate kareema alone in almost 4 months only asing Allah to wipe off my sins and also give shifa from those diseases which came through my sins. I'm badly affected by impotency, premature ejaculation and everything.

I am daily reading minimum 1500 times astagfirullah,
100 times 7 powerful ayat from Quran i.e. La ilaha illa anta subhanaka inni kuntu minnazAlimeen.
Subhannallahi wabi hamdihi subhanallahil azeem
And other 5 known and powerful ayats.
And also min 500 durood shareef

I'm reading this for last 5 year wihout skipping a single day. I'm honestly reading this for Allah forginess and also to get shifa for my many diseases. I am now becoming hope less and don't see any future for myself. Please advise what I'm missing or doing that Allah is not even listening.
