My employer is disorganized, my manager is weak, and the writing is on the wall.

So I think at this point I need to admit the writing is on the wall. For context, I have worked for this company for almost a year, and it's given me nothing but heartache. Before I hopped onto this company, I worked for a very vicious corporation that was trying to quietly downsize its staff. Even before that I was fired from a company that really liked me until I told them that I had cancer. And before that one I got fired from well was basically sweatshop from an employer that didn't like that I had a doctor's appointment on my first month of employment.

To make a long story short, my main grievances with this company have been: 1. My manager is bad at communicating and snaps when I have a question. 2. The workload is so bad that I have to do overtime in order to catch up with deadlines. 3. Everybody's blaming me for their deficiencies with Revit.

And now, I think I'm on the chopping block, because my coworker reported me to HR when we couldn't meet last week's deadline. I've been so burnt out for the past couple of months, I tried to stop doing that OT so that I can regain my energy. I did it at the most inopportune time, and now they're resentful.

I do feel like I did make a lot of mistakes during my time here, but I really think I made those mistakes, because the lack of work-life balance has caused me to become so exhausted that it's impairing my own judgment. And having an unapproachable manager makes it even more difficult to know what needs to get done and when.

I want to say honestly I look forward to my next job. I really do want to say that with confidence. But right now I don't really have a backup, and it's almost Christmas time.

What should I tell the next company is the reason that I'm looking for my next job? I want to tell them that I locked work life balance and had a unapproachable manager but I don't know if that will look good on me in the interview.
