I'm in love with a teacher I had in high school.
That's very problematic. Do you really think you're in love?
I really do, and they'll open so many opportunities for me!
Well seeing as they're your former teacher form high school and you're an adult now I think you being in love with them is fine. You're old enough to make that decision for yourself and I wish you all the best.
Oh crap I said it to myself again. I think it came out of self delusion.
I feel like you're confusing reality from fantasy and that can be really dangerous. I do hope you get yourself together to see if it is really worth pursuing after your previous teacher or if it is healthier for you to find someone else in your life that will not make you feel confused.
