Void from not having a real mother?

All the time growing up and even now I’m almost 23 I look for mothers in other people because mine never gave me the time of day. And it doesn’t work like I love my teacher and my class just ended and now I won’t ever see her again and I’ve been in tears over it not that I know she would care if she ever saw me again. And a bunch of other people is something wrong with me? I’m never going to have that I don’t know why I look for it.
