I’m absolutely atrocious at doubles what do I do

I’ve never felt so ashamed man, I was playing a dart bot and I was fucking miles ahead, only for it to catch up and win because I was stuck on a double. Actually, all three legs were like that. I had a checkout rate of 0/34. How do I lock in? I know bobs 27 and around the world but the thing is, I’m too bad at hitting doubles to even do those. Please help, I’m losing my grip on reality here
