Yep. I have. As I recall, I was in the exact same fix on my 25th birthday. So much so that I took the day off, decided champagne was the way to go, and promptly slept through the birthday party my friends had for me at my then boyfriend's house. Yes, I was there - just on the sofa. Additionally, I had to explain to my family why I missed the dinner they had made for me which was scheduled to take place prior to the party at the boyfriends.
Why did all this happen? Because I was absolutely sure no one would care a whit about my birthday and I felt utterly alone going though this so called 'special' day.
Yes, I know exactly how you feel. Don't do as I did and completely miss your 25th.
And -
Happy Birthday, Happy Love !!
