My friends bailed on me on my birthday?

Today is my 16th birthday and i spent the day with my mum and family, i had arranged too see my friends tormo as my two friends are going to conrwall and they couldnt come so i arranged it tomro but now they cant come as they are leaving early which i completely understand however my friend bridie was supposed to come but said she had no money so i made it somewhere cheap but then she said she couldnt come as she was going somewehere with my friend whos going to conrwall and my friend who is going to conrwall lied and made excuses because she wants too get the pill from the doctors. My other friend sally told me she was broke too but is going to manchester too meet a guy and my friend bridey is going as well even though shes broke. My friends sadie and lucy are coming though Im very grateful. But it just upset me my friends lied too me to get out of it and it was for my birthday. I sound like a baby but i spent the last hour crying, What should i do? (sorry about grammar i wrote it fast)
