Any advice would be appreciated

Hello, I am new to this forum. I need some advice plz. I have a 7 yr old who was diagnosed a year ago with absence seizures. She has been on Zarontin 3.5 ml in am and 3.5 ml in pm. She is a bit wild with this but the dr called and said her ethosuximide level was a bit low and wanted me to increase it to 4 ml in am and pm. I refused since that was her original dose and she had terrible nightmares. So we agreed to give 4 ml in the pm. After two weeks of the increase she was talking about self harm. Immediately took her back down to her original dose. She was back to being somewhat normal. These last few days she has been so indecisive. Maybe I like something or maybe I don't. Last night was horrible. She was saying she heard voices and was crying and covering her ears. I am so upset. When she was talking "crazy" with the increased dose about a month ago, the dr said maybe switching to Lamictal or Depakote. I do not want to try another med but I don't want her seizing! Has this happened to anyone! Please share!
