Friends’ response and what I’m making it mean

I put out a workshop and asked two good friends to share the flyer with others.
One friend responded but the other did not and I’m making it mean that she doesn’t think what I’m offering is valuable, that she thinks it’s too expensive for what it is etc. I don’t know why her opinion matters so much to me. I’ve just heard her talk about other people and services and I am extra sensitive to what others think, especially friends while I am building my confidence and repertoire.
She is very critical of others and I’m sad, annoyed etc at her lack of response to me.
