Hello iCandi and a belated welcome to the forums from me also.

I think a lot of people probably feel this about their jobs. Maybe not for the exact same reason as you, but they feel it, just the same. I'd say that if they haven't been telling you about something you are doing wrong, you can rest at ease. The fact that you have the job means that they (your employers) think you should have the job and really, when it comes down to it, it's their opinion that matters. I reckon there would be a lot of jobless people if we all assessed our own ability and whether we should be there or not...
