So I just need a place to put this, as well as some advice maybe.

I have depression, and it's mostly managed by a combination of medications. I can get out of bed in the morning, and feel fairly motivated up until around 1 PM. At 1 PM, my day at class ends, and I go home. I get in an extremely low mood where I don't want to do anything, and honestly even lack the energy to move from say the couch to my bed. There's not even a particular reason why, I just suddenly feel awful. It lasts from about 1 PM to around 5-7 PM usually.

Could it be that it's just a low point in the level of medications in my system? Should I change the schedule? Currently I take my medications when I get up (7:30 AM), and when I go to bed (around 9PM).

Any help is appreciated.
