You may not know the answers to these questions, and that's okay. Did you get a free, total, or both drawn? Did she mean the level was high for a cismale, for being ftm, for this point in your medical transition, or that is was high period?
The endocrine system isn't my strong suit. However I do know that hormone levels fluctuate and humans are known to exaggerate. Unless she gave you an actual number that was double the high end of average, I wouldn't be concerned if she isn't and you aren't having distressing symptoms.
If you don't trust her, is there anyone else you could go to that you do trust? Even if it's just for a second opinion on your levels.
