Who ever is saying ” stop worrying about the money”, either is bH comfortable enough that they have no need to worry, or has not had to invest in things such as seminary yet. That is a foolish thing to say.
Anyway.
Seminary in Israel and seminary here are SO different you cant compare them. The experiences girls get in Israel is just on a different level, a beautiful level. She just got there. Please please don’t make yourself sick over this. Wait a few weeks, a few months, and youl see she will make the best friends of her life there, she will meet amazing rabbanim, she will grow spiritually. It will be great.
When i was in college even, i was 5 hours away from home and the first 3 weeks i would call my mother everyday crying hysterically, i even missed a class or two because i could not function i wanted to come home so badly, i was so mad at myself for choosing to learn so far away…at about the 1 month mark, i calmed down and realized how great it was to be so independent, and my years in school were some of the best in my life. It takes a while to grow up and get used to being away from mom and dad. Give her some time.
BUT it is perfectly ok to fret that you have just wasted 21 grand, because to most people that is a fortune.
