>but it seriously bums me out
Talk to your manager. If you don't have 1:1s, ask to have routine meetings. If your manager can't help you, alleviate your stress, or guide you forward, look for a new job.
It's hard to really say anecdotally if things were fair or unfair, but your manager's job is to help you (and selfishly, for you, they should help you grow in your career).
