I really need some help, when I'm stress or out and about I really struggle to project my voice, the more stressed I am the harder it gets until I reach the point that I can't actually make any sound at all. I'm finding that because I can't make myself heard Which just adds to my stress I’m wondering is there a device I can use that would help me navigate my way around ie Saying words like excuse me, can you help any advice or suggestions would be greatly appreciated thank you.
