hey there, why does your teacher bug you/class sooo much, why do you feel so frighten towards her, and why do you feel nervous going to class? Ask yourself questions as if why she makes you feel a certain way and find a solution towards each one. For example if the teacher bug you or the class so much, my answer towards this question wouldnt be soo good because when i was in high school,,,if my classmate including myself felt some type of way towards a teacher, we would torture the teacher with pranks after pranks…. We would hide the chalks, add staple pieces to the marker so when the teacher write on the white board it made noises, one of the classmate would make a weird sound effect noise, and so on. But than again i was in a high school full of rebels in which occassionally we made few teachers literally cry running out the class… But lets think more of a positive note, if you feel a bit frighten by her, say to yourself constantly that her anger has nothing to do wit you, you're basically there doing the best you can,,, (she's probably miserable, and remember misery loves company) so wear a crystal rose quartz necklace or bracelet, that would spread the love to yourself and others, the crystal would trap the negative vibe releasing LoVe energy… And the feeling of nervousness before arriving to a class, you have to prepare yourself mentally, so before walking into that class run into the bathroom and close your eyes think of nothing NOTHING AT ALL, Inhale deeply, all the way deep til your chest rises, and exhale all the way out til your stomach is completely empty,,, do this three times, and if you like… each time you Inhale deeply say a phrase like (one for the mind) then exhale, second time inhale deeply and say (one for the center(heart) then exhale, and third inhale deeply and say (one for the soul) and exhale all your anxiety, fears, and nevousness all out. Go to class and as you walk in there, say to yourself, "her misery has NOTHING to do with me, im in it to win it" and go in class with a positive state of mind, do a great job, give them all you can be, and if she's still not satisfy, it doesnt hurt for you to break a smile (not in her face, she might get offended) but smile and that smile is to prevent any negative thoughts, and just think that her anger is just funny to you, and you have nothing to do with her misery :) the end.
