Sounds pretty intense…I definitely feel for you. I went from a out-of-town BY elementary to a pretty straight-laced (probably using this as a euphemism here) NY Bais Yaakov high school. I like to focus on what I gained (and I feel that I gained a lot from high school), but I’d be lying if I said that I was completely peachy with everything that happened there. Especially going in–I was totally unprepared for all the crazy politics, and I was initially very put off by it. But I sort of just learned to deal with it and keep my nose clean, and focus on what I stood to gain there. And now, what matters to me most is that I had a few really great teachers (that I am in close contact with even today), made some good friends, and learned lots of stuffs. I hope you were also able to get something from your BY experience.
Also, it sounds like your sleeping issues were unfortunately a big part of your high school experience. I am sorry about that. Hop you find a good eitzah soon. 🙁
