Jaguarbass, you are not the only one who feels the need to pray about things in your heart.
It is something I too was brought up with and it still influences my mind at times. I know that guilt plays a big part in it, and if you have family members in the "truth" it makes it worse.
Being aware of the falsehoods in the WTS doesn't free you. I don't know what does. But over time you will get over the praying before a meal and other demanding thoughts will go away. If you find yourself leaning towards another Christian Religion, know that it will be hard to accept. And for good reason. You will have to accept the Trinity, Hell, and a belief that Jesus was God on Earth. Too far a stretch for me to agree with. But you have your own mind and don't let it be polluted by lies and false hopes. Use logic and things will make sense.
But you must be strong and accept what your own logic tells you. What it is only you know.
