Toddler not sleeping

Need some major help! My son will be 2 in November and he’s slept with me since he was a baby bc he’s stop breathing in his sleep at night... well he doesn’t sleep through the night and literally tosses and turns ALL night until he gets up at 6am. I have to bounce him in the bed ALLL night for him to stay still... what do I do... I haven’t slept in over 48 hours and I can’t barely function anymore. Plus with connective tissue diseases and heart problems it’s very hard on me to bounce him all night but I do what makes him comfortable. HELP ME GET HIM TO SLEEP THROUGH THE NIGHT PLEASE!!!!
