Welcome and congratulations on the birth of your baby! You have a wonderful chance to increase your milk supply for him while he is still so young. Will he still latch on? If so, I would take him to bed with you and just rest and nurse and snuggle. All that skin to skin contact is wonderful for you and your son.
What sort of support system do you have? Well meaning friends and family often offer to help, so this is the time to take them up on the offer. A meal, a sink of dishes, anything that can help you focus on caring for your baby.
Good luck with this and we're here for you!
