Thanks for posting a query in health care magic.
From the description that you have stated it appears that you have a black eye, and every balck eye, especially if it is accompanied with dizzy spells should be CT scanned. Some base of the skull trauma can lead to black eye and needs to be ruled out. There is nothing wrong in being extra conscious. No need to blame it on your anxiety
Hope I am able to solve your concerns.
