What to do when you have to present yourself?

What to do when you have to present yourself? I'm in highschool and I have speech blocks. Mine arent severe but it's just so annoying. I always have stress to say my full name, sometimes it comes out fluently other times it won't come out. It does help when I breath in and out and put something like "my name is..." but today I had to present my self and it wouldn't come out so I did that trick but it just sounded weird because I was the only 1 who did that. Any tricks to avoid this?
