Spending my 21st birthday alone.

I’m going through a serious depression. I’ll be turning 21 in 11 days, and the way it’s looking, I’ll be crying my eyes out all day. My biological fathers new wife hates me so much that she planned their honeymoon so that they’d be across the country during it, my mom lives 4 hours away from me, my boyfriends family will be in Mexico getting his fathers teeth fixed, and it looks like my boyfriend will have to work that day. I’m so upset, I was so looking forward to my birthday. I just feel so alone.
