LPT Request: How to stop being the person who talks too much?

As title. I’ve always been a person who talks a lot, and I’m cognizant that I sometimes (probably always) tend to talk too much in conversations with people. I’m usually okay when I’m just talking to one person, but when there is a group, I tend to talk too much, especially if I’m nervous.

I ramble and add too much context and generally talk too much. Does anyone have any tips to stop this?

PS, I’m neurodiverse if that makes a difference.
