Sort of similar, I was handed business critical system to maintain on my own. I was new into the company, and new into that industry too. I was expected to handle business requests, establish good relations with users and run all meetings with them, Sort out the old backlog which was in a total mess, provide constant support, progress stories, create new stories. My manager threw me under a bus early on, we had a pre meeting catch up to decide what we'd discuss with business stakeholders. In the meeting I brought up what he mentioned and I genuinely thought he'd forgot to ask, his response "why would you think that..." Then proceeded to act shocked I brought this up and proceeded to contradict me. If I asked my manager for anything he'd throw it back in my face. I had 18 months of pure hell. Only after I left did I realise I was in a sort of abusive relationship. I heard later he said that my problem was I refused his help. It was a miserable experience, made worse because I pretty much always blame myself if something is wrong.
