And is there anything you can do to make sure you don't cross it? DD is 4.5 months and I am constantly tired (despite her only waking once in the night now), feel like I'm doing rubbishly as a mum, everything feels difficult, I wouldn't care if I never had sex again and I'm extremely highly strung which is most unlike me. I also feel like DP is getting exasperated with me and am not sure how much of this is true and how much I am projecting as he says he's not.
Are these just normal new mum feelings or am I losing grip on things? Depression is in my family so I think we all tend to assume someone is depressed when they are not necessarily, and I don't want to go onto ADs for no reason. Are there any techniques to keep afloat?
