Don't be too hard on her. I am not sure jasminerice has ever really encountered nurseries and people that use them, tbh. Obviously women (or indeed men) don't go around with silly smiles on their faces over-compensating through 'qualidee time' for leaving their children with non-family members during weekdays, and obviously children and carers in most nurseries build up family-like bonds a lot of the time, otherwise it would be a fairly disastrous setup, with children turning out wrong left right and centre, and everyone regretting it. Not to mention children forgetting who their parents actually were, which patently doesn't happen.
We've been tracking the outcomes of nursery attendance particularly closely in this country since about 1997. As it happens, there seems to be no particular disbenefit to children and probably some actual benefit, particularly in cases where mothers have minor or greater degrees of postnatal depression and so on, or if parents are poorly educated themselves or have disorganised domestic lives. As all nurseries are registered and closely monitored, we also know that in statistical terms, adverse events and accidents are probably less frequent than in children's homes. There may be a delayed effect for older girls in particular, in that we think they might be more likely to do well at school if they see many women engaged in the workplace in different ways.
So the reality of today's nurseries is a lot more prosaic and commonplace than many people would like to think. It's just another place that some families go, depending on what care arrangements they feel they would like to make, what they can afford, and what is available in their area. And that's all it is.
My own feeling on the OP's predicament is that there is a very good reason not to use nursery in her case, and that is that she feels very upset at the thought of leaving her child, so it seems to me that she is simply not ready to and she should reconsider her position. However suggesting that this means nurseries are a defective form of care is not a logical conclusion to be drawn in this instance.
