What do you think, as a DCP or single mom, should a soon to be SMBC worry about first in themselves?

what i mean is like red flags in yourself, and how you could possibly see them. for example, I worry I might lean on my kid too much? like, not depend on them for anything, but loving on them too much? how i see it, its like your kid will always be there. friends and relationships, usually fall no matter how much you love them, and its hard for me because obviously I want to care for someone. not saying this is the reason I want a kid lol. but idk, would that make my kid hate me later on?
