Different groups of people just "fit" differently together. I'm sure all of us have a little "bad employee" in them and some "good employee" too (excpet perhaps mother teresa). I think it's really valuable if you can actually take the "negative" voice and try and listen to what's true about it (and shun the crap). It's likely to help with your future. Likewise, take some time to think about what was really good that you did also.

More then anything though, keep positive about the new place. It's quite possible it's just a "fit" issue. A different set of employees will offer a different fit for you, and likewise their clientelle the same. Not every person is a good patient for me, some are, some are not. Neither of us is "bad" or "wrong" we're just comming from such different places that working together is not in either of our best intrests. Same thing for other midwives I work with.

I don't know you very well, the most time we've spent together was the Midsummer nights dream play, but you seemed to be there when you were supposed to be, learned your lines (and songs) as best as you could, from that I feel like I can extrapolate you're probably not an ineffective employee, but probably just the situation didn't work so well for everyone.

I think it will feel good once you're really in there! Hang in there!
