Coming from a mostly healthy relationship with my mom, and having a mostly healthy relationship with my own son... It doesn't sound sweet latching onto mother figures. It sounds like a recipe for disaster. Why? Because that's an inequal relationship. You're walking into peer relationships, placing the other person above you. For one thing, as you're not a child, they have no impetus to protect you / put your needs above their own / assume the role of someone who is actually a mother. For another, putting people up on pedestals? Rarely works, and often ends badly. People don't like being up on pedestals, as a rule. It's restrictive, confining, and hugely limiting. It denies them their freedom to act in any way which is not narrowly confined to this tiny little block of arbitrarily defined behavior, decided upon by someone else. So not only will hey be going about their normal life, refusing to stay up on that pedestal you want them on -disappointing you- but many people will often get deliberately antagonistic about it. Because they don't want to be on that pedestal. And will actively push back against attempts to place them on it.
But mostly it's coming into a relationship (professional or personal) that you've decided from the outset is inequal.
Foundationally inequal relationships (parent child, adult child, teacher student, boss employee, priest supplicant, etc.) are all strictly codified to protect both parties. It doesn't mean that abuses don't happen. Clearly. But whether it's a social or legal construct? It acknowledges the high potential for abuse, and attempts to minimize it. The inequality only exists in a very narrow range of applications (the child grows up, the student graduates, the employee can quit /or be promoted /or go home from work). Outside of those constraints? I'm an adult. My mother has no power over me. I'm not at work. My boss has no power over me. Same token, the powers they do have? Are also limited. And codified. People still abuse or take advantage of those in their power, but it's considered both wrong AND there's recourse. Because the duties are clearly laid out
None of those -and other- safety measures exist, when you're the one placing another person above you. As you're finding.
The trick, IME? Stop placing people on pedestals. Even bosses, priests, cops, judges, etc. are still just normal people -that you are completely equal to- who are fulfilling a role. Your boss may outrank you at work, but nowhere else. Priest may outrank you on church, but nowhere else. These mother figures? Don't outrank you. They're just normal people. That you can still learn from, respect, like, enjoy... Without popping them onto the mother-pedestal, or trying to enact a relationship that doesn't exist.
One way to stop doing that? Change the wording. Might sound meaningless, but there is a huge difference between a mother and a mentor. If someone is a mother to you? That's very different than if someone is a mentor to you.
