Hi Dahlia,
You're welcome
There's a lot of good advise here .
I like the " Playing in front of friends, small venues , Also envisioning yourself playing in-front of people ." I use myself while playing a piece or a tune .
I've thought of another thing that may help.
You're a classical musician you read well . Try to find a Jazz or Popular band
to play with . You'll find a lot less pressure while playing with a bass and guitar
or Bass, drums and guitar . You may find a great feeling while playing live and
increase your confidence this way . Then shine as a solo concert pianist !
