My body is a cage

For the second time, second day in a row, I wake up feeling drained. Got enough sleep, woke up early, but I can hardly hold my head. So drowsy. So drained. I blame in my head the medicine course that have been messing me up for the last three months. I feel the need to do things, but my body fails me. It affects my mood, my concentration. The constant, endless, yet meaningless fatigue is drowning me.
I feel so heavy.
I feel like drowning.
