I hope this doesn't come off as overly cynical, but this is a wildly popular misconception about what HR is for and does. Google "HR is not your friend."

Some companies might have a mediation program to mitigate employee/manager disputes, but the vast majority do not. If OP had lost the confidence of their manager and doesn't see any options to regain it, then there is nothing left but to move on.

If that's so I should never leave my company. My own situation wasn't directly comparable but I was stuck in a role I ended up in; HR helped me out big time. There core focus was: how do we make everyone excel in what they do, accepting naturally that every individual has its own weaknesses.

That's an excellent philosophy and I wish more managers/business had it.
