8 months old baby sleep regression

Hi guys I have a question for you,my almost 8 months old baby is having sleeping problems,until he was 6 and half months old he had a good routine slept well trough the night and had great naps to but when he hit 6 and a half months suddenly started to wake up at the night crying and he wouldn’t go back to sleep unless I rocked him and than put him next to me in our bed,and now 1 and a half months later he still having sleeping problems and separation anxiety he has his first two teeth already coming out and he still sleeps next to me in our bed,if I put him in his crib he starts crying and won’t fall asleep I don’t know what to do with him..Am I the only one who’s having problems like this? All day I keep receiving email from baby apps that at this stage he should sleep in his on room and he should sleep well etc..and now I feel that I’m doing something wrong..to be honest I’m not that great with routines I’m trying my best but I’m alone all day with the baby I have to run errands and take care of the house and the baby all by myself because hubby works really late so I can’t do the same stuff with the baby everyday at the same time...is there anyone else having the same problems as me?

Sorry for the looooongest post ever.

🤗😍😘
