I don't understand my testosterone results

Hi all

12th day after quitting fin, my doctor would only allow me to get a serum testosterone test.

The results are in: 11.2 (the range is 8.4 - 28.7)

He said no further action is required. I ahve no idea how to interpret this but it seems low and my testosterone before fin I am SURE was high, I was full of energy, lifting wights 3 times a week, super high libido. Now I am depressed. I have and am developing new symptoms

What can I do?
