How do I, a person who deals with being excited and anxious by getting overwhelmed, teach my kid how to deal with being excited and anxious in a different way? I have no idea.

The other parent isn't helpful (doesn't get excited and anxious in this way).

There is good advice in this thread! One thing I learned recently is tapping alternately for anxiety...tap fingers alternating hands, 1 tap left hand then right etc. In medical setting recently I did left right etc with toes.
@mtechman thank you, that sounds interesting!
