SaysMe, it’s really not easy to advise someone to quit with “only” a year and a half left to a degree from a “real” school. I would likely advise you to stick it out if it were only a question if the work, the time, and even the pressure.
However, the ruchniyus issue is a different matter. I don’t know the situation, and I don’t know you, so on this you really do need your mentors’ input. Try to work out some way of getting through this intact; shiurim, Partners in Torah (even better as a mentor), books, etc. Run some ideas past your mentors, and see what they think.
Another thought; will your current school accept any online or Touro credits so that you can minimize your time in campus? Or are you already maxed out on Sem credits?
Hatzlachah!
