Is it normal for me to consider my teacher like my mother?

Hey everyone, this is my first time here on "Is it normal?". As I was googling "is it wrong to have a motherly love towards a teacher?" I stumbled upon this website with approximately the same question. So I entered the link and I read what has been said about in the topic above. Anyway, this is not the reason why I'm writing this text.
It's been two years now since I've met my teacher, she was my teacher last year and this year too. She's the kind that is strict but at the same time has the most adorable, most uplifting personality. I can't even tell you how cute she is when she laughs. She helped me a lot since last year and influenced me a lot too. She also helped me decide what I want to do when I'm done with high school, and it is the study of french literature, since she is a french literature teacher. We've never had any deep conversations really, and I'm shy to start up a conversation with her sometimes. I can't help it though, I really want to talk to her and have decent conversations with her, but I sometimes feel like she doesn't want to talk to me, and this brings me down. But that's not the point. My parents have been divorced for 5 years now, and I've been living with my dad the whole time, while at the same time I used to go every weekend to see my mom. Now since last year, my mom traveled to France and is now living there with her new husband. I'm very cool with what has happened until now.
I don't like to admit this, although it's true, but I consider my teacher as my mother, since my mother wasn't there for me when I needed her. To be honest with you guys, Miss... was there for me when I needed her. I used to call her up for a chat on a break at school and she would sometimes be there, some other times no. I share with her my writings and she really appreciates them. But there was a phase in which I felt that she was ignoring me, so I wrote something about it and sent it to her, and she loved it unknowingly that it was about her. Thing is that she is always on my mind, like she's more on my mind than my mother is. I think about her all the time, and sometimes when I feel like she hates me or she is ignoring me, I get all skeptical inside and feel uncomfortable in my own skin. This goes for days sometimes. I always dream of her, which is weird because she's always there, and my mom isn't. I once had a dream of her that she was angry at me for no reason, and that was the first I ever dreamt of someone being that angry at me. It is told that, if a person dreams of another person who is angry at them, this means that the person who dreamt has committed wrongs towards the individual he dreamt of. So I decided to go and excuse myself for whatever I have done something bad towards her or in general. But I never did.
I am aware that she is a mother and a responsible woman that has a job and a family to raise, but all I want from her is to understand what I'm going through. Sometimes I feel like all I want is to cry on her shoulder. Once.
I want to get closer to my teacher, as if she was my friend or my big sister. That's all I want, really. And I don't know what to do. Some of my friends tell me to go and talk to her about how I feel and share with her my thoughts, others tell me to just drop it.
So please, if anyone could help, please tell me what I should do. This is really important for me.
Should I tell her how I feel, that I wrote her a text and tell her about my dreams?
