呢2句有冇錯grammar, 點樣可以表達得好d?

Finally, her son ends up with getting anxiety disorder.


However, if their children bear a lot of works at an earlier stage,
they cannot handle it well.

Hope that you find it useful.

Finally her son ends up with getting anxiety disorder.
我會先行瞭解：焦慮症 是 anxiety disorder 了。
我認為直接寫法，較為易於接受呢！
However, filled with so many things in （such）early stage, their kids cannot keep up at all.
"so many" 可作 idiom 看，你有看過 such many 嗎？又如果要用 such，我會提議在括號的地方使用呢！當然如果不是為了加重語氣，不用為妙！
