Does completely changing your sleep schedule change your mood?

I used to sleep all day or only for a few hours for a month like insomnia. A few days ago I abruptly changed my sleep times and slept at night. I feel messed up now like exhausted and really depressed for a few days. (I felt like this in beginning too when sleep was irregular.) I just got my period too so maybe pms is adding to it. Can abruptly changing your sleep schedule do this to you?Does completely changing your sleep schedule change your mood?yeah for sure it does even more than that!! for me i really hate vacations for that reason, i sleep all the day and i don't care for anything else!! the period of studies i feel that i'm returning to my normal case. the sleep schedule has an important role in your psychological life, you have to know how to organize your own and you will see that it'll give you your responsibility and a part of your personnalty. be sure about that :)
Does completely changing your sleep schedule change your mood?
yes until you get used to it. Getting enough sleep can be an issue. Take naps helps, just shutting your eyes helps.
