All my friends just bailed and it’s my birthday.

Today’s my 21st birthday and me and a group of about 10-20 people were supposed to go out for brunch and a movie for my birthday. I’m literally sitting in my bedroom crying because everyone bailed. Either late last night, this morning, or didn’t even respond when I asked if we were still on. Happy fucking 21st to me. I may just go out to a bar and have my first legal drinks alone. I chose somewhere cheap and a cheap movie so it wouldn’t be a financial burden and no one really gave any good excuses as to why they were bailing. I’m just kind of depressed right now. My family is 5 hours away and I’m alone now. I just need some ideas of how to cheer myself up.
