Why is my translation different from theirs?
我不想要你因为我变得消极。
I don't want you to become demoralized because of me.


If you want the meaning 'because you make me depressed' try 2.


我不想要你因为你让我变得消极 。
I don't want you because you demoralize me.


In 3. I think you are just trying to apply the type of syntax you know to Chinese.


从早安后的早餐,到晚餐后的晚安。
From breakfast after Good Morning till Good Night after dinner.


If you take out the adjectives from 3., you have:
4. 从早餐到晚安
from breakfast till Good Evening


从早安后的早餐,到晚餐后的晚安。  



  Why didn't it translate to: From morning after breakfast, till dinner
  after Good Night.


after breakfast is : 早餐后 but you have 'after Good Morning' = 早安后
after dinner is 晚餐后，after Good Evening is 晚安后
