Keep getting rejected pitch letters for client

Ugh.. I just have to put it out there into the world because my mind feels like its going to burst... I have been working so hard to promote and find press for a client who I truly believe does have a great product/artistic work... Her work has been selling like hotcakes and shes been featured on a lot of local news stations.. But im finding SO much rejection as I pitch her to some of the big guys like NBC, FOX etc..Major Magazines... And im devastated for her.. Ive tried switching the pitch..I wish I could share it because her story is really incredible and humble... Ive tried not giving up and reaching out multiple times.. But just find rejection everywhere we go... I just truly need someone to say don't give up!...And maybe a prayer that just one large name would say yes to us... Please pray these people change their minds.. Some huge universal event where they just think.. Gee.. I should give those guys a shot! Of the thousands of rejections.. 1 big yes would make it all worth it..And despite working hours and hours and hours to get this into peoples hands all the nos are starting to take a toll..Please could someone pray for us? Anyone been in a similar boat?
