Does anyone feel really depressed when they don’t workout?

The past week I didn’t go to the gym at all due to conflicts. Nothing else changed, my workload is the same, I keep checking my cycle but it’s not for another few weeks, I still eat the same meal prep.

The only thing changed is not going to the gym. I feel really horrible and have no motivation to be productive. Im neglecting school and work, it almost feels debilitating. I also struggle with depression and manage it with diet and exercise, after adverse affects from medication. I wish I was more proactive and thought of this when I took my break:(
