Please answer. Kik xoxo_angel_xoxo

So I'm the nice girl. I'm the girl you can got to for anything. From advice to answers. You call me. But I'm getting tired of it. I do alot for everyone. Try to help everyone. Make them happy. But I get walked all over and stepped on alot at the same time. I help kids alot more then needed. I give people answers to everything. I help kids pass grades. Like whole grades. But the same kids will push me in the hallway and give me dirty looks. I don't like seeing people sad or upset, however I hate getting stepped on. So what should I do? Kik me if needed
