“what did you or would you do with a gap year? if your still single, and have NOTHING to do for a WHOLE year????”
“its for the WHOLE year that i have off!! but its for kids!! also hopefully ill be married by then h’h!!”
The premise of your question is if you are not married yet when you finish college. If “hopefully ill (sic) be married by then”, your original question does not apply. Although of course even then you would still have to find something to do before you start grad school.
If you are still single- I third the motion of learning in an adult program in E”Y. You have stated that you were home school and did not attend a frum high school, went straight to college. So you have not had limudei kodesh classes in quite awhile. You would gain a lot from them. Considering your current challenges in a non-Jewish college, I think you would find it so nice to be among other frum women, in a totally Jewish environment. It’s not necessarily putting your life on hold for a year- you can date in E”Y too. And what you learn would be a great preparation for life and marriage.
There might be learning programs in the US for young adults too that you can attend, if you do not want to go far away.
If not, or if you get married this year, you should re-consider a job. After another year of college, you will probably be more employable and might have better luck with finding a job in your field of interest. Your parents might be supporting you now, but you can always save for the future.
If you can afford to forgo the salary, you might have more options as an intern or volunteer. Another great idea if you want to explore research is to intern or work as a lab technician in a research lab.
