Being too tired to be sad

My mind is too occupied for me to get too affected by my depression nowdays

I know this is a tickling time bomb until a extreme burnout, but my rotine nowdays is pretty much

5:40-6:50 wake up, bath, clothes, coffee

6:50-7:30 way to work

7:30-12:00 work

12:00-13:00 "lunch" break

13:00-17:30 work

17:30-18:20 way to uni

18:20- roughly 23:00 uni

23:00-23:20 way back home

23:20- roughly 00:40 make food (tonight and lunch tomorrow), eat, bath, sleep

Main problem is, every weekend im filled by immense dread and emptiness. What do?
