Chareidi institutions don’t usually have websites unless they are kiruv type schools. Try ohr somayach. Its more kiruvy, but definitely chareidi. It will be less stressful of a jump/ transition into the chareidi world from public school. Regardless of the hashkafa of the family you grew up in, there are a lot of things that frum jews who lead somewhat sheltered lives do differently than you would be used to in a public school. Trust me, I know.
If you can’t understand this sentence, then seek a more kiruv style yeshiva.
Frum yidden should aspire to daven to the aibishter with so much kavana that they feel that their neshama was uplifted during their davening and they would not notice anything else going on around them, chas ve’shalom.
Just so you know, this sentence was written in more yeshivish type of language, which is a mixture of yiddish and english. The non-kiruvy style yeshivas require you to have a stronger command if the yiddish language in order to blend in more socially. Also, there are people who are not baalei teshuvas who learn at ohr somayach as well because they have never learned gemara before.
Hatzlacha!
