Why does my brain freeze when I try to use the VSO word order in conversation?

I’ve been studying Welsh grammar for six months and I can identify the Verb-Subject-Object structure perfectly on paper. However, the moment I try to form a sentence out loud, I instinctively slip back to English word order. Does anyone have tips for internalizing the 'Welsh way' of thinking so I don't have to translate mentally every single time I want to say hello?
