Nicole, I can really feel what you're feeling. I'm also in an urban low achieving school district in the South. I love teaching but after 4 years the burnout has set in, especially in the last few weeks, all focused around discipline issues, student lack of effort, and school/district problems. I really do care about education and I want to change things. I love curriculum and teaching and planning, but everything else SUCKS so bad, and we just try to "shut our doors and teach."
If you are not accepted, try not to let it get to you. Another year "in the trenches" is not so fun for us as people, but amazing for us as teachers. I feel strengthened by the type of students I have compared to some of my colleagues in better districts. People like you who know the hardships are the people who should make the changes! Hang in there!
