I hold my breath while peeing?

[Firewood]

I never really thought about peeing before it was just something I did. Then I read a tweet on Twitter about someone who does that now when I go pee everytime I get tons of anxiety and I sometimes hold my breath now. How do I stop doing this?? I've tried focusing on breathing while peeing but my face gets red even though I'm breathing. How can I just forget about this and start peeing normally again? I've tried sitting too. This is really bothering me
