Exhaustion
Are you taking B12? In a sublingual, nasal spray or shot? Are you taking iron?
When did you last have labs done? If you're really exhausted now, you might want to get some done now instead of waiting a couple months.
When you say you think you're not getting enough protein, what does that mean? How much are you getting?
