Below,Under,Below,Under???

My English 底處未見底, I am feeling very sad....

我猜想你的中文片語可能是想說：
低處未見底 (直譯：where it is low is not the bottom yet)
英文解：
(1) Where it seems bad is not the worst.
(2) It is getting worse

我又猜想你可能是指 (2)，即是 [愈來愈差]。

如果是，全句可譯作：
My English is getting worse, I am feefing very sad.

I missed a very good point from 001 jenken.lai1，so I would want to make an amendment:
全句是： My English is poor, and it is getting worse; I am feeling very sad.

首先更正「底處未見底」應該是「低處未見低」，看來你的中文也是「半斤八兩」。

My English is poor, I am feeling very disappointing.

sad是悲傷，你不用為英文差而悲傷。我代你表達你只是對自己有點失望。
要死了人才sad，你會好過d。

當然你要bad亦可以，不過亦是太悲。poor只是差(窮)，知道自己窮便找辦法賺多些回來。既然是「低處未見低」即是未到最底，所以我不用at the bottom。講下笑。

Good luck.
