Sleep more

omg just had to write it down i slept 12 hours every day for the past 10 days XD

So since school started, this september, I have found my self in a very messy sleeping disorder. I sleep randomly through the day, wake up at two in the morning and do homework O_o, sleep in math class, just a mess.
It started when i went back to school, i still was working 31 hours a week. After the first month I was running out of batteries, and becides being a full time student, and working part time, I had alot of extracuracualr activities. So I quit my job, but I am still stuck in this viscious cycle.
If anyone has an idea on how to fix this, I’d love to hear it:)
