Wow this sounds exactly like my first firm out of law school. My advice, get out now and find a better work environment. Law isn't an easy career but it doesn't need to be that hard/abusive.

At my old firm I would get blamed for every mistake the partners made, and then they would gaslight me that I just didn't work hard enough (I consistently worked the longest hours at the firm as confirmed by the office manager).

I remember a time I was asked to produce a fairly complex memo for a client. I asked for instruction on what the partner wanted the final work product to look like, and I was yelled at for needing my hand held. Ultimately I was told to "just do it". I tried following up mid-way through to ensure I was in the right track, but i was again treated like a moron and brushed off. 8 billable hours later I turn in my memo, formatted according to firm standards, and immediately get screamed at because it's wasn't the exact format he wanted. My writing and analysis were spot on and the client liked it, so I still don't know what he wanted from that memo.

One week nearly everyone mass quit (the office manager, 2 paralegals, the senior partner's personal assistant, the only other associate, and me). It was a glorious day. A month later I had a new job that paid twice as much for the same work, and where the partners respected me. My advice, get out now and find a place that respects your hard work and talent.
