Is it normal i feel this way??

My math teacher and I are so close, we have lunch together hug frequently and get along very well.. I am a female as is she and we just have this mother daughter connection I don't have with anyone else not even my real mother.. I often get jealous when she helps other students or does something with them, I have kicked over the hallways garbage can because she hugged somebody else I got lunch detention though because I didn't have a legit reason but, she Is always on my mind I think about her all the time no matter what I'm doing.. She knows some of my history and she really helps me through hard times, I can barely go the weekend without crying over her, she is my biggest motivator, she makes me want to get good grades because I want her to be proud of me..I have no idea what im going to do over the summer or even spring break.. she is my life literally she is in my mind, heart, dreams everything. I love her and im not sure I can get over her when I move on to the next grade..
