In a sense – in a sense! – it’s a good sign that you find it hard to daven. I know it sounds nutty. But it shows that you recognize that the same HaShem Who decreed that Leiby a”h should be killed is the same HaShem Whom we daven to, the same HaShem Who runs every aspect of the world. It shows that you don’t approach davening as a meaningless ritual.
that being said, we still must daven.
Gut Shabbos to all.
