Thanks for all your replies.

Your suggestions are very good, unfortunately with my fatigue I find the prospect of leaving the house almost terrifyingly exhausting, however I realise that I need to seek social interaction in order to combat my social isolation. I have to start with baby steps, one thing at a time.

Yesterday I went to mother's group and I was almost panicking before I left the house, but once I was there everything was fine so I know I will be able to do it confidently again next week.

We're trying hard to work out Jude's sleeping arrangements so we've just bought a cot for his room which will be better ventilated and ultimately cooler at night for him to sleep more comfortably. I moved his bassinet to the living room where there's air conditioning and I took the advice Snacks gave me and tried to resettle before he fully woke up. He woke up anyway, but because he's right behind me I was on the case in 2 seconds and now he's asleep again. That's the first time I've ever successfully resettled him so I am very pleased.

My husband took a week of paid leave to be home with me and sort things out, too.

I have considered PND which is why I ended up seeing a clinical psychologist. I don't believe I have PND, just extreme fatigue which makes me situationally depressed, not chemically if you know what I mean.

I guess all I wanted was for someone to understand me and to know what it's like to be this completely fatigued so that even leaving the house seems like the most daunting task ever.
