How do I deal with my neighbors?

I don’t know what to do anymore. My upstairs neighbors bang so loud on my ceiling that I get woken up out of my sleep several times every night. I’m epileptic and this is seriously damaging my health. I have gone up and asked them to quiet down myself, talked to my landlord several times, and now have called the called several times. Cops say they can’t do anything and landlord said they can’t either.

I can’t move, that’s not even a possibility. I’ve lived in my apartment for years and have had several upstairs neighbors. I’ve never had an issue getting the right amount of sleep. I genuinely don’t know what to do anymore. Does anyone have advice? At this point I’m ready to sell all my stuff and move into my car. I can’t do this anymore.

Edit to add: I’ve tried earplugs but then can’t hear my alarm for work, I’ve tried sleeping pills but also can’t wake up for work. I can’t bang on the ceiling back because they just bang back on the floor for about a minute.
