Help! I’m about to lose my mind !!

My son will be 10 months next week and has hit a terrible terrible sleep regression. He wakes up AT LEAST 5 out of 7 nights a week at almost 2:00 am on the dot !!!! He is cutting at least 3 teeth and is on the verge of walking, he takes naps, sometimes one long 3 hour nap and other days it’s 2 45 minute naps ... we try to give him oatmeal before bed to sit on his stomach and are trying to stop giving him bottles when he wakes at night (per his doctors suggestion that he should be able to sleep 10-12 hours without a bottle and if I don’t start sleep training I will be getting up with him every night and rocking him to sleep until he’s 12 ) but some nights it’s just the last resort to get him back to sleep. I don’t know how much longer I can do this schedule of me going to bed at 11-12 (I clean and do bottles and laundry after he’s in bed at 9-10) then having to get up with my son from 2-4 then him waking back up usually at 7-8. It’s mentally exhausting and I take the brunt of it bc my husband works everyday and I’m a teacher on summer break so it’s mostly me getting up alone. He’s not on board with me at all trying to let my son cry it out and training him to self soothe and put himself back to sleep. I get so frustrated and I know I shouldn’t but I seriously need help, ideas and guidance.
