Lots of hugs for you. I understand what you are going through. It is not at all silly to feel depressed because you feel that you have not made friends at work. It is very important to have a support network. You are a first year teacher and need support. Many first year teachers have strong feelings of failure. It sounds as though your co-teacher is not helping you to change that feeling. I recommend you do the following things: - see if there is a mentor program at your school. If not, see if you can find someone whose teaching you admire or respect, and ask if they can mentor you informally. -find out if your school district has a counseling program for its employees. If so, go to a counselor and tell of your concerns. It is very helpful to speak to someone else about your situation. It can help you feel more empowered and come up with solutions. -allow yourself to make many mistakes. You won't be perfect this year, or anywhere near perfect. That's okay. No one is during their first year. It does get better. You will get better. -your co-teacher is putting you down because she feels insecure. Understand that people who feel secure in themselves will support you, not put you down. Seek out secure people. Try to hear your co-teacher's comments through a filter: think about whether they can help you to improve. If you feel they can't, ignore them and move on. -to improve relations between you and your co-teacher (and this is very important to your daily reality), you need to focus on the good things she does. Comment on them. Make a list of them and keep compiling that list. Doing this will make a difference in the way you feel about her and the way she feels about you. You can turn this situation around. You need support. Seek it out. You made a great first step in that direction by coming here. Now you need to find support at your school. It's there. You just have to uncover it. Good luck, keep us updated.
