Your students do care. You are making a difference. You are the only stability in many lives. You are not wasting your time. What you do does matter. And YOU MATTER.
If you are a teacher, you were called to impact each student as much as you can. So don't get discouraged and don't give up hope. You can do amazing things. When you start to feel those feelings of inadequacy, it helps to surround yourself with positive co-workers who are there to listen. Others have walked the same road and have experienced the same challenges and frustrations. Your co-workers can help give you words of encouragement and lend an ear.
Just say this to yourself right now if you are feeling discouraged:
I am somebody. I was determined to be successful when I started the school year and I'll be successful when I finish this year. I am powerful and I am strong. My students deserve my very best today and I'm determined to give them my very best.
