FTM with a two week old help!!! ☹️

I have a two week old and he's great during the day he sleeps all day, he's well fed and changed when it's needed. But as soon as it's time for bed at night he becomes very fussy he will cry and cry even after being breast feeded and he will want to be feeded more then the day and it seems like he doesn't get full and will cry and cry and nothing seems to calm him down. Our bed time is between 9:30 to 10:30 the latest and he will end up sleeping around 3am sometimes 5am. I've been very sick since I gave birth to him in the hospital. Now I'm home and would like some tips on how to put my baby to sleep or what can I do? Or is there anything that I have to buy?
