I'm obsessed with my teacher?

So I had this teacher for my freshman and sophomore years of high school. Sophomore year was when I really began to become obsessed with her, I looked forward to her class every day, and sometimes I would randomly just start smiling in her class because I loved her so much. Then sophomore year ended, she wrote the sweetest note ever in my yearbook (giving me a bunch of advice, telling me that I can call or text her whenever something goes wrong, etc etc) and I didn't know how I was going to go without her during junior year. I promise this is nothing sexual in the slightest- just the thought of that makes me cringe- but junior year I continued to love everything about her, and I loved passing by her in the hallways and my heart would start racing whenever I saw her and when she waved hi to me it would make my entire day. I would always glance into her room to catch a glimpse of her, and I would constantly think about her. Then senior year came. Senior year was this past year, and I was going through a lot of stuff and I've never had issues like this in my life before, and she was always willing to listen and did so much to help me through those things. I would always look forward to going to school because I knew that I would see her and get to talk to her more. This lasted for a few months, but then I noticed that we began to grow apart a bit, and she almost seemed annoyed when I would go talk to her, but that could also just be me overthinking things as usual. So last week was my last day of school because I'm doing an internship during May, and on my last day, she gave me two hugs and did seem a bit sad that I was leaving. Anyways, this was my first week of internship. And I'm so glad that I don't have to go to high school anymore and I love my internship and being in the "real world," but I miss her so much and keep wanting to call or text her but I know that I shouldn't because I don't want to be annoying. I have a journal that I write in periodically, and I write about her a lot in it. I think that I love her because I've always felt like an outsider in my family and don't have especially strong relationships with my parents, so she almost stepped in as my mom this year. Idk, I felt so weird writing this because it doesn't sound normal at all, but I can't help myself, I just love her so much and already miss her even though it's only been a week of not seeing her everyday. Any suggestions on what I should do would help so much, thanks for reading this!! xoxo
