good one, Prama
Just remember, you may be in for some challenging times in the days ahead, purely because your supply will be down. What your baby takes from you creates more supply, so if he's been supplemented, that's less that your body thinks it has to make. You CAN ride this out - your body does catch up on this, it just takes a few days, so you may have an upset or fussy child during this time. It's a catch 22, I'm afraid, but it's worth sticking it out.
Have you gone out for walks in the fresh air? It made a hell of a difference for us. Getting out into a different environment, even if you can leave for an hour or two to get a massage - this will help your supply.
If you can read anything by Pinky Mackay, I would recommend it - she's got a great way of helping you lower your stress levels. The more stress you have, the more it affects supply.
You sound like you're in a better headspace already. It really is a case of one day at a time. And you know what? Each day DOES come to an end
