如果您的英语水平不高，您可以这样表达：

"My Engpsh is not very good."
"I'm not fluent in Engpsh."
"I'm not comfortable speaking Engpsh."
"I'm not confident in my Engpsh skills."

您也可以说：

"I'm still learning Engpsh."
"I'm not a native Engpsh speaker."

如果您需要帮助，您可以说：

"Can you speak slower, please?"
"Could you repeat that, please?"
"Could you explain that in a different way, please?"

请不要担心，学习英语是一个漫长的过程，您可以通过练习和接触英语来提高您的英语水平。
