I am 15 years old and sometimes i am on a high and think i am on top of the world, lately that feeling has dissapeared. i am in 5th years doing 3 highers or A levels, and i can admit i am a little stressed about some projects and essays i have to complete. Now my best friend is being really nasty at me and is barely even telling me anything, not even about the facts she has a new boyfriend she always tells me these things. Also i work nearly a 12 hours shift on a sunday and i am really tired on a monday so sometime i dont go so i cant catch up on sleep, and yesterday my childcare teacher moaned at me and asked in front of the whole class why i was off mondays quite alot, i tell her i dont think it his her concern as i catch up with the work within minutes and she goes i dont know what is wrong with you these days, and i dont know about you but i took real offence to that. And above all that she is extremely patrionising, i said to her that i was grouchy because i didnt want to be here as school was really starting to get on my nerves and that i would love to leave, and she said well why dont you, but what she doesnt get is i want to do well and do my exams and hopefully pass like last year. But at the moment i am at my all time low, with friends, family and school. What can i do?
