I hated and lived in fear of my birthdays in earlier times. Not inviting people and celebrate would have made me socially more awkward as I already had been, so I felt myself forced to act acceptable and do as people expected me to, 1 month before I was issued, got sleeping problems because of it, were afraid of that day, got stomachaches and simply wanted to run away from everything. The last year I simply ignored social expectations of me inviting everyone for a celebration. So my birthday event was a Lan party with my closest friends, we played Games all night, and additional there was some beer and a fruit cake I had baken, but not more, and it was wonderful and we had lots of fun and for the first time in life my birthday was the way I liked it and I had fun. I can only advise you to ignore social expectations, and simply celebrate your birthday exact the way you feel best. Be it a quiet day for yourself reading, a Lan party with your friends, whatever. But make it a lucky day for you.
