Is it okay to say anything in davening? I don’t have much to say right now in davening other than selfish requests and selfish venting. Mainly I just want to talk to Hashem about my sadness and pain and how much I miss Him and want to be close to Him. I also want to talk to Hashem about the good things, but only what is true in my heart. If I’m excited and thankful about a certain blessing then I want to express that without fear that it’s wrong not to be equally thankful for another blessing. I don’t want to be selfish and petty about my pain. I don’t want to be ungrateful. I feel tired and worn down even though my life is very good. People don’t understand. They can’t. And nobody in the whole entire world has the time and patience that I need. Maybe that’s an incredibly selfish motivation to daven, but it’s where I’m holding right now.
It is permitted and correct to talk to H-shem the same way that you would talk to your father. Anything that is important to you, and you would want to express it to H-shem is allowed, as long as it is done in a respectful manner, and not something that is against H-shem’s wishes. When we daven, and talk to H-shem we can and should be intimate in our conversation with Him. Tell Him everything that is on your mind. This is part of having and developing a relationship with Him, and it is a good thing. Keep it up.
