I have so many things to say here but they’re not really forming anything solid… One thing which I repeat often: In my experience, if you look at the people you know who’ve been affected by a hard time they’ve been through in life vs. the other regular, wonderful, good people (and they are) you will see a big difference in character and emotional maturity. And whether you choose to go into a therapy-related field or not, you will IY”H come out of everything a much stronger person (look at your screen name!) and one way or another, I suspect you will use your experiences and devote time and energy to helping people who have faced bullying in life. Hang in there
If you would consider switching to another yeshiva (smaller?) at some point, where you can get a fresh start and not get lost in the shuffle, that may be something to think about. Also if you have any hobbies (music, writing, kitchen, photography, whatever it is) devote time to it when you can- you’re allowed to have something to identify with by choice that you enjoy.
