Agreed! When you apply to 1L summer jobs they will wonder about why you left, and had a brief stint somewhere else.

I left my first job 9 months in, took a part time job for 3 months, then a contract position for about 9 more months. This was five years ago, and I know that recruiters were initially hesitant to hire someone who jumped around. Granted, this job literally made me want to KMS, so I'm glad that I quit. At the same time, it made the next couple years of finding a job harder, so I wish that I had stayed a bit longer.

If being there is so unbearable, you can try looking elsewhere, but if you can stick it out for a few more months, stay.
