How to not sleep for 12-13 hours?

I've always been a big sleepyhead but especially in the last few months my most monumental struggle has been sleeping anywhere from 10-13 hours a night :') I have an alarm clock across the my room that I have to get up to turn off but even that hasn't been helping. I just turn it off and go back to sleep. I set it for 11am this morning after i fell asleep around 1am last night and still slept till about 2pm today :') I'm really only awake to go to work at this point and it's getting tough!!!

Any advice??
