That’s a really rough situation you’re in, and I totally feel your frustration. Now I want you to think about what I have to say, please don’t just read it once and disregard it. I want you to think about WHY you want to go to seminary in Eretz Yisroel. Now once you’ve figured out your reason/s, think to yourself: am I able to sacrifice my experience, and all I may gain from it, I’m order to get this Mitzvah of ????? ?? ????
In the Zechus of this Mitzvah, may you be Zoche to become the best person you can possibly be, even without experiencing seminary in EY. I believe that on this Zechus you will also be Zoche to find your proper Zivug with ease. I don’t believe you will suffer by sacrificing (especially) something as big as this. Hope that whatever choice you make works out!
