I have many speech blocks, can anybody help?

I have many speech blocks, can anybody help? Long ago I used to stutter, Ive gotten better but the main problem I face nowadays is speech block. It’s a symptom of stuttering where you just cant say the word without forcing it out or saying “uhh” for as long as it takes. It typically happens with the first word of the sentence, but sometimes it can happen at random times aswell. School is about to start tomorrow, and I have experienced getting embarrassed and laughed at for struggling to say my name, especially that it starts with a vowel so it makes things ten times worse. Typically when we have new teachers, they go around the class asking our names, everyone would say their name quickly, unbothered, except for me, whos forced to say “uhh A…” and get laughed at by the whole class. How can i fix this, because Im definitely not excited for that to happen tomorrow. Also another thing about me is Im able to say “my name is A…” without speech block, I can even say it without speech block in my language and the sentence starts with a vowel. But when it comes down to me saying just my name, where the teacher is looking at me, and everyones listening to each other saying their names, I struggle then and there.
