First defer to your doctor not anecdotes on the Internet.
So for kids that have aggression and type 1 hyperactivity it can calm them down so they are processing at a more normal speed and thus improve focus and anxiety.
For someone like you who sounds like a type 2 inattentive I would expect it to make you more tired less motivated and do nothing for your anxiety.
The combo I have seen most effective for your type is either an activated medicine like Wellbutrin or a combination of a extended release stimulant with an SSRI.
I'm not a Dr, pharmacist, therapist, or psychiatrist. What I am is diagnosed type 2 who has talked and worked with lots of other adults with similar diagnosis.
Again go talk to your Dr.
