I think we have all been there at one time or another L-J. This happened to me at work a few years ago. I had a manager who found fault in everything I did and in the end I went off sick with work-related stress. I put in a grievance against him and he was moved out of my team.
No, you are definitely not inferior L-J. Ask whoever it is that is making you feel this way what their problem is. It sounds like they are the one with the problem and not you.
