I'm so sorry @LouisePlease - Please keep your head up best as you can. I know it's difficult, but I went through this with my best friend a few years ago when he was accepted to only one of nine programs despite having spectacular undergrad and MA records both from very prestigious institutions, along with certainly very strong letters. He ended up very happy in his current PhD program which is an excellent fit for him. I'm sure there will be good news soon.
