Severe anxiety

Joined a small generalist team less than a year ago with one MD and VP as the only analyst.

Came from a successful job before hand (not in the same industry) but always wanted a crack at IB.

Opportunity seemed fantastic at the time, direct exposure with a VP and MD.Long story cut short, I've developed quite severe anxiety.

The smallest task makes me feel crippled with anxiety and fear in the case I f*** it up.

VP has left now so it's just me and the MD. He is incredibly difficult to work with and shakes with rage and anger whenever I make a mistake and gets very irritated when I even ask a question.

What do I do?

I have read several analysts threads on here about their anxiety and experience. It always seems worse than mine (in terms of hours). Am I just being weak?

I worked incredibly hard to get here, but now I just feel like a shell of the man I used to be.
