Low t at 16, don’t know what to do

I’m 16 and I show practically every sign of low testosterone levels, I have no motivation, I’m exhausted by afternoon every day, sometimes earlier, I can’t maintain an erection, and there’s probably some other stuff I’m missing. I’m getting a blood test soon to confirm it, but I’m pretty sure I know this for definite. The problem is what I’ll do afterwards, I know I’m too young for trt and that it’ll probably do more harm than good, but this doesn’t stop me from wanting it, I’ll probably get it as soon as I turn 18. I know it’s possible to marginally increase your t levels through lots of exercise and eating healthily every day, and i guess this is possible but it does just make me sad that I’d have to spend the rest of my teenage years following a strict diet and spending most of my time in the gym when most other lads my age get to go out drink get into fights and do what your supposed to do at this age but I’m kind of just venting now, does anyone have any advice?
