being triggered

When you get  triggered by people and there's things coming out your mouth even before you've thought them and you can't control or know what it is that your saying shouting back at them. Is part of autism, I can be in a conversation with 2 or more people then i here some one saying some thing to me about some thing else then i'm triggered by what they have said to me It makes me have a melt down or lose control then i can go back to the conversation i was having with the 2 people, Then same some one distracting me again triggers me. Is this all part of autism, I don't know how to stop it. Its just so instant and some thing wild takes over me.
