there is a teacher at school who helps ppl with problems and stuff and i have been trying to keep it a secret so ionly told 1 friend... who then told another then about 5 people new and some wernt even my friend, then my history teacher saw my scars and told another teacher and that teacher told someone else and i had to tell my PE teacher cuz i couldnt do PE because of it, then my friend way "worried" about me so then told ANOTHER teacher, i had to tell one of the teachers why i was selfharming and everything but i lied because i didnt want them to tell my parents cuz my parents would justr get angry at me so now there is one teacher who keeps checking that im ok and she said she wants to see me tomorrow so i dont know if i should not tell her the real reason or if i should tell her cuz i feel so selfish and everyone hates me even a girl in my class called me an attention whore but i really didnt want all these people to find out, now i have no friends left my parents dont care and i dont know what to do....? helppp
