Can I be a teacher?

Making the decision to be a teacher in an inner-city, under-funded, low-performing school that has a student population that is struggling against a number of factors wasn't really something that I thought about. In addition to not being able to read, my kids are struggling against poor parenting, bad classroom management, learning disabilities, social/emotional disabilities, not to mention the lack of resources at home and at school. Sigh.

I'm starting to think that I'm not cut out for this. I can't do this job correctly and succeed in all the parts of it. I can't coordinate the program effectively, recruit students, check-in with instructors, keep in touch with teachers/administrators, and attend meetings WHILE RUNNING MY OWN CLASS. I think it's physically impossible to succeed the way that I want to, when I am stretched so thin - emotionally and physically. I've been on the verge of tears all week, and I don't know why.

I'm trying to meet all the needs of the specific kids in my program, because they all need so much help and attention, and I don't think that I can do it to this extent. I can teach them what I can teach them in 2 hours after school, and that's where I have to stop. I can try to teach them life lessons in that time, but I can't change what they've learned their whole lives, what they see when they go home, and the ineffectiveness of their teachers during the day. I have to learn how to turn off. 

I just want to change the world and I feel like I'm not doing enough.
