Why do I love sleeping more than doing anything else?

It's not like I'm trying to be lazy, I just prefer being really cozy and sleeping then going out or doing anything really, I have depression and I take anti depressants, I just rather sleep which I can't always do because I am a mommy but still to me, a day off is me relaxing and sleeping for over 12 hours r more. Its not like I don't want to create memories. I just really love sleep. I feel more myself afterwards too
