Just wanted to add to your 'hug load'. You sound like you're doing a great job during a major life adjustment. I remember thinking how ill-prepared I was and questioning my decision to be a mum as well. There's no right or wrong way to feel and people all cope and feel differently. It's great you have a professional and private support network in place too.

Have you tried baby wearing? Maybe then you could do something while he's awake and squirmy - a walk, chop veges for dinner etc. As PP have said, forget the housework and what you think you should be doing. The support network you wrote of can do the urgent stuff while you catnap/rest. Are you eating properly? It's really easy to neglect yourself when you're so worried about everything else, but a healthy mummy makes a big difference to how you feel and cope. Let your DH look after him for a little - yes, it's hard to let go, but totally worth it to see them forge a strong relationship and for the break you get.

And yes, it does get better...baby settles, your body adjusts to short naps only, you find it easy to fall asleep at the drop of a hat etc
