26M, 21-22% BF

I've always understood that men shouldn't consider bulking until they're less than 15% BF. I started at 200lb in October and 28% BF and until recently was seeing consistent success. But here's why I'm thinking about bulking:

For the past 2 weeks, I've been staying in the high 160s and 21-22% BF. I have less energy than I used to, sleep more yet feel more fatigued, and am at a point where I'm not gaining strength in the gym.

While their advice varies slightly, all the men I know say that I should start bulking and build muscle.

My base has been 2,000 calories and 100g protein. If I were to go through with this, I'd start out at 2,200-2,400 calories and aim for 120g protein. While most online calculators project my TDEE to be 2,400 calories, my appetite has shrunk so this would be a considerable adjustment.
