Lost my giftedness from sleep deprivation and gaming addictedness, please help

I'm 13. My IQ was dangerously high as a kid, but now it's in the shitter. I'm slower than the average student. I'm big dumb.

I got a B in Real Analysis. B+ in Thermodynamics. A- in Women's Literature. My hot girlfriend dumped me.

How will I become the next Elon now?
