Oh, no.
Listen, this is so early in your child's life, and although there is a lot of confusion and possibly pain later on (though I hope not!), this is really the most confused, sleep-deprived and my-whole-life-has-changed-what-the-hell-have-we-done it is likely to be.
Have you got a sling? New babies like to be carried about, especially colicky ones.
Sleep when the baby does. I know it's hard (and I didn't take my own advice on this one, as I hated being woken unexpectedly), but do try. See if you can sleep with the baby and feed him in bed. That will save you time at night, too.
Try to get into a bit of a routine so the new life is at least predictable.
If you can get any family/friends to come and stay, that could help lighten the burden.
Meanwhile, I hope you know that it's very unfair of your DH to pressure you by telling you he's "not happy"! What the hell does he think you are doing - egging DS on to have colic, or something? It's not as though you have the magic "off" switch which ignorant outsiders are always huffing loudly about! Okay, he has some anxiety and stress issues, but this is still unfair on you. If he has a therapist or knowledgeable GP, he needs to talk this through with them, and learn some coping strategies. Not tell you "he's not happy".
