Brain fog

Brain fog I’m 25f, I noticed in the recent years that I’ve been struggling with conversations ,in the sense that when I’m talking to people I’m very slow in forming sentences and in the recent months I tend to struggle in finding the right words to use when I’m building a sentence . I always struggled with stuttering in stressful situations ( like during exams ) but I never had a lot of issues in talking with my friends and be quick with my words. Have this happened to everyone else?
