6 month old HYSTERICAL at night

HELP, I just need some reassurance that this is totally okay and he'll get past it or some tips on how to make it better. My 6 month old has never slept through the night and is even further from doing so. From the time he goes to bed at about 8:30 he wakes almost every hour crying! More often than not he can only get back to sleep if I nurse him. If I get him back to sleep without nursing him He definitely won't stay sleep for a long time. I am exhausted and stressed and don't know what to do. I keep telling myself he'll sleep through the night when he's ready but it only gets worse 😩
