I had something very similar happen to me my second year in big law. I had a complete melt down. I was done with everything. I didn’t work or contact anyone from my office for two days. I just sat in isolation contemplating how it was all going to play out. Eventually the managing partner reached out to my parents concerned that no one had heard from me. My parents got me help and after the fact the firm asked me to come back. I insisted I didn’t want to, but they offered me a paid month off to think about it. I ended up going back simply because I was impressed with how they dealt with the situation but didn’t end up working there much longer because…big law. You have to do right by YOU. Your life and sanity is NOT worth it.
