HELP PLEASE!!

So my son is 6 months old he got his two bottom teeth wen he was 3 months, and recently he’s been teething becuz of his top two trying to come out but he’s also been not sleeping at all at night and eventually passing out in the morning today was the latest compared to the last few days he went to sleep around 1030 this morning. I need help fixing his schedule and I’m lost I have no family near me to help and my bf could care less cuz he leaves for work by 8am. I’ve tried everything I could think of to get him to stay asleep but he wakes up screaming as soon as I put him down and if he naps over night it’s tiny cat naps 15-20 minutes at a time and then he’s up! He’s been very fussy due to the teething but I’m running on no sleep and attempting to make a morning schedule routine is near impossible cuz I end up passing out myself or staying up straight thru the day cuz I cnt wake up if I do sleep. I need help ASAP if any other moms have advice or have tried and successfully fixed there baby’s sleep schedule Plz plz plz anything is appreciated!!!!!!!!! Thank u in advance!
