i am bilingual and my stutter is way worse in spanish than it is in english

i am bilingual and my stutter is way worse in spanish than it is in english I used to stutter much worse in both English and in Spanish but since I've been an "adult" my stutter is much better in English but still really bad in Spanish. I believe it is tied to my anxiety, i was a very anxious child. Anybody else here have a similar experience? Any advice on how to improve that aspect?
