Is this normal?

I need help. I have a crush on my teacher. Well, two teachers, but I’ll explain more.

For context, I’m in highschool. Ever since I was little, I remember having crushes on older woman. Like, 20 to 40 years older than me. I never actually wanted to pursue anything with them, it was just that they were hot.

About 4 to 3 years ago, I started getting more into shows and movies, and I started getting obsessed with the relationships in them. For example, this show called supergirl. There’s a ship called Supercorp, it’s between 2 female characters. I watched a bunch of edits and was into the show for about 1.5 years until it started to fade little by little.
I then got obsessed with this other show (it’s more known): Dr. House. Again, I got really into a ship between two male characters (House and Wilson). And again, the obsession faded. The thing is that, yeah, I had crushes on the characters in the show, but I was wayyy more into the characters relationships than anything. I would write mini fanfics about them, but never including myself because it just felt weird you know?

Now for the really weird part. I’m so sorry if you’re reading this and you’re a teacher.
I also always found comfort in older women but especially female teachers. I had mini crushes on them but not to the extent of what I started having at the beginning of this year. I have an English teacher, let’s call her Miss G. I wasn’t starstruck when I first saw her, but I think I definitely got obsessed about a month in. I wrote about her in my notebook. I started by writing down her outfits, then her birthday/age, then LITERALLY EVERYTHING. I know so much about her, but all I’m going to say is that she’s 53 years old since I think that’s important. Jesus Christ, I even know her birthday and that she dyes her hair and what she focuses her money on and… I know lots about her. I used to write down EVERYTHING she said while I was in class. And yeah, she’s hot okay? But I’d never been this obsessed with a teacher. Dude, the creepiest part (I think) is that I found her and her husband’s Facebook and I managed to find her approximate address. Anyway. Ahem. The obsession was insane. Like, super insane. I gave her a shit ton of gifts, looked at her pictures any time I missed her (which was on the WEEKENDS), and visited her classroom almost every day. But eventually, my feelings faded. I still get weak in the legs when she talks to me, don’t get me wrong, but I think I manage my emotions better around her now.

Then there’s Mr. JT. I’ve always been a lesbian. Always. I only ever had a crush on Dr House and maybe a few other fictional men, but NEVER IN MY LIFE have I imagined myself with a man. Then JT arrived. The crush arrived around… well, like half of the year was already gone. I didn’t write down everything about him, but I still think about him every day and write scenarios about me and him or him and other people and I tried drawing him and oh my god I’m so weird. But yeah, you get it.
I don’t know if this is important, but a few months after my JT crush, I developed a crush on a guy my age. Mind you, it’s the guy I SWORE I’d never like and that I defended our friendship to everyone that shipped us. I’m pathetic. Oh, also, me and my parents have a good relationship now, but they used to be insanely strict in the past. They made me feel unsafe and I still think about it. If that’s important, I could elaborate on what they did.

I guess what I’m asking is: what the fuck is wrong with me? Is it normal? Should I get help?
