I get well deeply. --有语病吗?

不是。

不通的. 想说"我已经好多了"?

I feel much better.

well 没有比较级 (get well那种well)

语法上没有问题
但是感觉很别扭
deeply没必要加吧

Obviously no one understand what that.

I don't even understand why is there a deeply at the end of the sentence.

I feel much better. As mentioned by the previous poster.

I get well >> Mean I'm recovering??
I am doing fine???

Don't really understand what you trying to convey.

这通顺吗？想表达“我已经好了”吗？你写上你想表达的意思我们才能给你最准确的答案啊
