Is it proper grammar to write 'nervous to' without the word 'too' being in front

[Samwise Gamgee]

Is it proper grammar to write "nervous to" without the word "too" being in front of it?

I am nervous to...(can it be written this way?)
I am too nervous to...(I know this is correct)

Hello Samwise Gamgee,
No, you shouldn't say "I'm nervous to..."
It should read "I'm nervous about ....." because you want to let someone know what is making you so nervous. You can also use "I'm nervous because...." and again you're talking about what is making you so nervous.
The reason that "I'm too nervous to...." makes sense is because now the speaker can now use the "to do" verb after it. This is when you want to let someone know what action is making you so nervous.
For example,
"I'm too nervous to jump off of the bridge."
I hope this helps.

Oops. Sorry, there are too many "nows" in the 4th line.
