It’s a very difficult decision.
This is why Touro is so amazing. I can’t even imagine being in the atmosphere I am now for 3 years of basic courses, dealing with the whims of each instructor, without a social group. So I empathize with your struggles.
On the other hand, it sounds like you’re halfway through, which is honestly the hardest time to pull out. You already likely have a considerable financial investment, so besides for losing future income, you have probably depleted your savings somewhat. Besides, you REALLY don’t want to have to repeat all the courses you’ve taken in the future.
If you’re pushing yourself for As, then I would consider accepting Cs and just focus on finishing the degree with minimal work. In the end, all that counts is the paper, and you can always do other stuff for grad school. Also, take summer classes so you can finish it ASAP.
At the same time, get involved in the community. Go to shiurim, do chesed, etc. It will help immunize you to ruchnius issues.
So that’s my advice. Stay in school and finish your BA, but take the pressure off yourself, and work on increasing your social connections in the Jewish world. You can take it or leave it 🙂
