If Religion was used for control by higher people,it begs the question why were all the founders of these religions Poor people? and not the rich?
Absurd understanding by atheists again,as for your prayer.
I have one thing to answer you.
Pray Tahajjud,Tahajjud is a really really strong prayer,and it has had many effects on people. So pray Tahajjud in around 2-3 AM in the night,atleast 11 raka'as.
and say this in dua'as
"huwal-awwalu, wal-aakhiru, waẓ-ẓaahiru, wal-baaṭinu, wa huwa bi kulli shay’in ‛aleem"
This is a dua against doubt. it'll help Insha Allah.
