Incredibly, absolutely, acutely….

All you have to do is use an online thesaurus and look for synonyms of VERY. There are probably at least 30 or so choices. A couple that come to mind: extremely, quite,

You could also use 'extremely'.

I am "ACUTELY" self-aware. This is simply a synonym to "very".

I’m not sure of the context. Do you mean that you are aware of a situation? Or do you mean that you are insecure?
