翻譯句子sentence

The subject and object in your translation have turned opposite.
I would translate it into:

After all, my coldness is just to protect myself from the people surroundingme/ my surroundings/ the cruelty (I face) in the real world ....

You can put whatever you think is appropriate after 'from'.

Anyway your tenses are wrong.

其實我的冷漠只是想保護自己.

Indeed, my coolness was simply to protect myself.

冷漠 - cool, not cold. coolness (noun)

let me try,


Actually, I am sedate for protecting myself.

你的說法有點中文式英文，應該是這樣：
Actually,I am cool because I want to protect myself.

Depending who is speaking to whom.
A guy would say :Let's cool off a little, it's for your own good. (gentleman)

If I'm a girl, I might say : Let's cool things down cowboy, I need some protection. (taming the wild)

heeeehaa!

Actually I indifferent only I want to protect myself.
我覺得係咁^^

我查到係：
實際上，當我冷時，我只想保護自己。
but唔知啱唔啱，希望可以幫到你啦^^
