Is my testosterone bad for 19M

For the past year I’ve felt low energy and mild depressive symptoms. My motivation has been at an all time low and my libido is somehow worse even though It should be at its peak at this age. My blood test showed the following values: LH 5.1 U/L FSH 2.1 U/L Prolactin 255 mU/L Estradiol 54.1 pmol/L Free testosterone 0.340 nmol/L Testosterone 15.45 nmol/L DHT 305 ng/L SHBG 25.7 nmol/L My thyroid’s values were good overall.

I went to an endocrinologist and he told me I’m young and in range and pretty much dismissed me. I’m wondering what I should do.

Any advice would be appreciated.
