My 4-year-old daughter just started headstart school last year has been acting really ugly lately and it's really stressing me out. I think she is picking up other kids habits at her school, because she never used to do things like this before she started school. I've also witnessed some kids in her class acting out as well. I'm already going through alot at the moment and she is just adding fuel to the fire. Everytime we go out in public like to the store, the mall, etc., she acts out by screaming at the top of her lungs and then she falls out on the floor when she can't get what she wants in the store. This is so embarrassing, especially the way people look at us. She also likes to talk back to me, saying really nasty things, which she never used to do before. I'm starting to think I made a mistake by putting her in school now. I don't know what to think right now. My mind is all over the place at the moment. It doesn't seem like my meds are helping me any either because I've been feeling more depressed these days. Does anyone have any suggestions? I don't know how much more of this I can take.
