Gonna need help with this...

Gonna need help with this... So In our country, summer is almost over and school is coming in 2 days. In the first day of our school, we introduce ourselves in front of the class. And I guess you already know my problem here. We have different teachers for each subjects, so probably we're going to introduce ourselves atleast 5+ times in front of class. Last school year I stuttered while introducing myself, it was like "I...I..-I--I-I-I am... My name is John~full name", and I don't want this to happen again. What should I do? I am currently stuttering while talking to my parents right now because of the pressure that I'm feeling. Is there anything that can help me with this?
