I Lost 20k Gems in OTJ

From 50% winrate in OTJ drafting (historically 60%+ over 3 years) getting no removal, no bomb mythics (opened Pitiless Carnage P1P1 5 times), and conceding to bombs like t3 oko + t4 oko, and from a similar fate just now going 1-3 in Arena Open, I have lost 20k gems in total thanks to OTJ.

Where do I go from here? I don't even play Constructed or Brawl. Do I grind the precon format for the next year? How do I hold all these tears...
