My issue is making me want to lock myself and never speak to human beings

My issue is making me want to lock myself and never speak to human beings I never used to stutter not in English nor my mother tongue.. recently I’ve been stuttering, repeating myself, wrong grammar, and embarrassing pronunciation It has been happening a lot and its making me cry internally. Its like i have a lot to share and talk about and I’m finding a hard time expressing my emotions or thoughts on topics with people from work and friends because i keep making a fool out of myself with the way i stutter and bad choice of wording.. Why is this happening out of a sudden and how do i enhance my speech skills .. :(
