Yeah, it's not always easy, but keep in mind the character is a character first and if you like them, there's always going to be someone else out there who has similar tastes and likes what you like.
Treating your OC like you would any regular character probably involves a level of creative responsibility and distance at the same time. Yes, you made this character, but you shouldn't go into conversation or thinking of you and what you put into the character. Think of the character and the story you've created for them like you would a story you have published for people to read already. Just like a fandom character you're character has a backstory, a personality, events that have happened in their lives, and you should have enough of it written out somewhere that you can go back and check yourself whenever needed. Don't look at them as being malleable and easy to change things whenever you want. You created their canon already, so unless it is something that needs to be changed, don't. The more you alter just because you want to, the more you stop looking at the character as a current being and start seeing them more as a being-in-progress that you can keep shifting things around on.
I play comic characters too, and sometimes writers change things for the most ridiculous reasons that make no sense. And the audience usually reacts to it unfavorably because you never understand WHY those changes happened or what use they have, especially if they end up radically changing something about the character. So when writing an original character I look at things the same way, don't change things needlessly, because if you do, then no one will see who your character is and they will start to expect inconsistency from you. This isn't to say you can't reveal things you hadn't brought up about your character before, but your character feels less inconsistent if any big reveals that happen don't fundamentally alter the character. The reveals should add to and explain things that maybe didn't make sense before, not create more confusion.

If that makes any sense.
