Okay, I’m a frum girl just starting graduate college and I’m not desperate to get married, either. I really want to, of course–it is something I constantly daven for–but I know I’m not quite ready. Please don’t call yourself desperate! (that sounds really bad!) When Hashem decides that the time has come, you and your bashert will find each other, no matter which side of the ocean you are on or what you are in the middle of doing. With emunah, decisions like these are easy: What does Hashem want me to do right now? Think about which decision you will appreciate or regret in the future. What path in life will make you a better person?
Just because your grade level already went to EY doesn’t mean you can’t benefit a lot from going now. You can try for being a tutor or madricha, or go just to learn. There are so many programs for so many ranges and backgrounds. And don’t worry about “what will people/shadchanim think” because you are doing what is RIGHT for you and your avodas Hashem and anyway, a solid eved Hashem should be impressed by your dedication to growth even if you’re not a starry-eyed fresh-from-bais-yaakov. And like others mentioned, you can date in EY.
Hatzlacha!
