As I remember, Jesus only offers 2 prayers that are wrong.
For instance, being in public and being loud about prayers is wrong. Praying in repetition, as though you can charm God into acting, or that God would be impressed by your ability to recite lengthy show prayers perfectly, is also wrong.
There may be others.
I am sorry you're going through this. That sounds horrifying, but I believe that since you're alive, God is gonna use this to make you a pure and powerful vessel for his will. Keep your hope and eyes on God, and know he's not out of earshot for his children.
I would ask, if maybe having your eyes open while you pray would help? I don't know if God requires us to close our eyes, perhaps just bowing in reverence would be enough? I'd ask God what he thinks about that, but I'm positive he'd probably not be insulted.
I have other questions but they get into things other than prayer. Prayer is good, I'll leave this comment there. Prayer is good, so I know God wants you to pray.
