I have a small lawn mowing job but times are slow and I had to quit volunteering due to my lack of time because of the amount of homework I have nowadays
If this is all as we are talking about, the remedy is for you to do things that make you feel stronger and more competent and more powerful. Do you have a job? Do you have a strong volunteer life where you can see your competence develop and see others feeling like you are good at what you do?
If all this is true, then it sounds just like me! I've noticed that I'm pretty much in love with her, and I feel quite often that I'm weak in a lot of areas, despite my strong mind. When I have other things to focus on I don't worry about het so much but once I start feeling dependent and weak again I go right back to being in love with this teacher.
It's weird how attached and dependent on her I am. The other day she wouldn't let me borrow a book that I wanted to read and I thought I had began to annoy her by asking, so I started making myself feel distant from her like I was mad at her. And I have even felt possessive over her because I get jealous of all the things other kids get to do with her that I don't (such as staying after school with her). I seriously think I have some emotional stability and relattional problem, too, because none of my other friends feel like this about teachers, especially of the same sex.
I remember reading, in high school in one of those books written for high-schoolers about the emotional stuff that happens at that age (in other words, an educationally oriented book, not a porno book or psych book) the comment that "Girls sometimes get 'crushes' on a favorite female teacher." It was pretty offhand and did not treat the phenomenon as an issue, it merely noted it in passing. So I guess what you're experiencing is pretty normal, if it made it into a textbook way back in the day. (Won't tell you what day, but it was long enough ago that such topics were less regularly discussed.)
Just to take a stab at it, you probably like her because she is a safe, nonthreatening, idealized person who also has some power, who is nice to you, so therefore affirms you. I can tell you from experience that when feeling relatively powerless at a given moment in life, someone else safe, nice and with power can be a great person to get a crush on. I've done it often enough with men I know in business, much to my embarrassment. The main rule I make for myself is not to let it get so out of hand that I do something or say something about how I'm feeling. I do allow myself to fantasize all I want, it's comforting. I notice that when my powerless feeling passes (work shifts or a tough project gets done and I feel on top of the world again), the crush often passes too. Sometimes I even wonder what the hell I was thinking. I just sort of take the fact that it happens as one of those natural parts of being human.
Don't know about the boy thing, except that in our society boys are more powerful than girls, and men of course have more power than women. Maybe it's all about not feeling very powerful right now and wanting some! Nothing wrong with that, either.
If the wires cross every now and then and one fantasy tries to make it with the other fantasy, just try to keep it sorted, and to work out some real-life things that will get you real-life wins and satisfactions, so you can feel on top of the world without having to use your fantasies to get you there. They aren't bad, they are sort of a way to emotionally self-soothe. But it's better to work out life plans that give you as many active strokes and satisfactions as possible, if you can. Real-life positives make you feel more powerful, and you then don't need the fantasy life as much.
