Prayer

Hello, I apologize for your time, I am a gentile trying to figure out the proper instruction for one being afflicted based on the verse "Let him sit alone and wait". Although I read from (English) Rashi that this is an expression of waiting, I thought "Yidom" also means silence, supporting the Pirkei Avot that nothing is better for the body than silence (I think). I'm asking because I'm wondering whether a person experiencing afflictions that would be a literal version of pains that the prophet talks about, and I am wondering whether it would be better to pray continuously or be silent. Moshe said a very short prayer that was effective to heal Miriam, so I have been simply asking for forgiveness for my sins since we learn from Tehillim (90+?) that our sins are the only thing that we can complain about and I believe that these are the sources of our dismay. I've stopped prayers of praise based on H' saying about Miriam that if her father spat in her face, would she not dwell outside the camp (I think)? Also, I read from The Divine Code that gentiles are discouraged from offerings although they are allowed since it is difficult to obtain the proper intention, and I have applied it here since people are able to control my heart/mind somewhat severely with technology and I'm not commanded to praise, so it may end up a Chilul H', Heaven forbid. If you could please offer some advice on the proper way to repent and regain life peace and happiness the most effectively, I would appreciate it. I also wanted to ask about the word "Naval". I have seen it translated as vile and withered, maybe with other vowels. In the verse, something like, "vile and unwise people", could this be directly translated as withered with these vowels?

On Weekday Morning service, Az Yashir is followed by Yishtabach. On Shabbat and Festival Morning service, Az Yashir is followed by Nishmat and eventually Yishtabach. Then the following prayers are recited on Shabbat and Festivals: HaEil B'Ta'AtzUMot (only on Festivals) ShoChein Ad B'Fi Y'ShaRim UvMaKaLot Yishtabach, which is the concluding prayer of Pseukei D'Zimra. 1. Where does Nishmat prayer end? 2. Why are the first words of each paragraph said aloud and emphasized (meaning the words listed above)?

Suppose I’m in shul. It’s during a time silence is mandatory, such as prayer or Torah reading. I am sitting next to someone who seemingly doesn’t know or care and keeps asking me a pressing question. I refuse to answer because of the mandatory silence, so he keeps on asking me louder and louder and more persistently trying to get the answer. Is it preferable for me to ignore him, which would cause him to keep talking increasingly annoyingly? Or is it better to make an exception and answer him, which would satisfy and silence him? I’m asking because I recently had a situation like this, and walking away or changing seats wasn’t an option either because of the crowd size.
