Wishful thinking

I have always had an ok relationship with my mum but I met one of her friends and she’s like me but older and wiser and I just love her. She’s literally been there for me since the day I met her.

I can’t help imaginary wishing she was my mum. I’m 28 so it’s not like I’m immature. My mum has done some really hurtful things against me. I can’t help but wishing I was this other woman’s daughter. I’ve never felt like this before. And I feel really bad for thinking this way.
