Health visitor

So anyone else got a health visitor they can't stand... my youngest will be 9 weeks old on Thursday and she's had a right rough start in hospital for 3 weeks born 6lb 10 currently weighs 7lb 2.5oz. We've now finally been told she's intolarent to dairy and that she's just meant to be small. But my health visitor in getting it saying she should be gaining at least a pound a week and am I coping am I depressed because of the stresses and stain of her being admitted to hospital. Then the final blow am I struggling because my first baby was stillborn at 38 weeks and my angels dad and middle childs dad(same dad) isn't involved anymore

Is my partner helping out with our baby. Then says I think your depressed just because I cry once a week... ermmm am I over reacting so angry.. they all try and make out our little lunar is ill but all tests come back negative. Her jaundice was cured with uv lamps there's nothing wrong with her I cry once a wee cause the likes of her our stressing me out making me doubt myself...
