My iman is at an all time low - duas not being answered

Im really struggling in life right now. Im in a downward spiral everything feels like it is going wrong. This past year im going to be honest I cant recall one dua being answered, i make dua for things that are simple, some extreme yet still no change. Im struggling mentally really bad i dont know what changes I can make in my life ive tried everything. I pray tahajjud regularly, make istighfar,daily quran, donate weekly, dua after every salah, dua before opening fasts.

Not one thing I asked for has come to fruition, i know duas are answered in 3 different ways but how do i keep going along this path if nothing good comes out of it. After a while I fall into sin because I get frustrated, astagfirullah which I know is wrong, every door feels closed. I call allah using his different names, my doors feel closed, what can I do
