I think I know how you feel. I've been there too.
It was sad, frustrating, even upsetting.
At the same time, I believe that such feelings can only make thing worse for yourself. Is not that you should not feel them, but recognise that the first effect they will have may be to just make you feel worse.
Personally I would go to my manager, ask a face to face meeting and express my feelings.
I would be careful not to blame others.
Be calm, it may be that this not the truth, so your manager is not expressing their praise but thinks you deserve it.
I would focus the talk on how I feel. I would try to understand if my manager cares about it (if they does, generally they would make some effort to improve on that).
And if they doesn't, I would look for another place; if I have to work most of my life, at least I want my manager to care about me as a person.
Most of the time tough, I found people that cared. I hope you do too 🙂
