((MMM))
Sounds like shame coming up for you - if it wouldn't be too uncomfortable you may ask not to have your birthday acknowledged. I've respected that when others have asked in the past.
I dislike mine right now as I'm in a transition between no partner, no family (though I intend to create my own 'family' someday) - I'm essentially alone very frequently. I love to other's birthdays, family gatherings and celebrations/holidays - I love surprising and planning for things. Truthfully, my partners have been less than stellar here - all of them have said to me at some point "I wish I was as thoughtful as you are".
Growing up birthdays were big so I actually don't mind the celebration part but I'd never plan my own. I admitted to my Ts this year that... I really wish I had a partner or something so that I actually HAD someone to coordinate. Which I know sounds sorta bad, but my Ts normalized it - it's normal to want that and it happens in many partnerships/families. It was a big step for me to realize this because I've always dismissed and minimized a desire for others in my life.
My sadness about my birthday is always about my accomplishments/progressions, and disappointments in myself regardless of any celebration so in a way I do hate it. I don't like the attention at birthdays (re: singing, or strangers knowing, or really saying anything to people) but I do a lot of performing, speaking, introducing myself to strangers as part of my hobbies and work (and personality - if I see anyone alone and/or nervous in a group I try to say hello) so anyway... I don't mind the attention but when I'm feeling super ashamed I get a lot of internal messages. On the outside I cope well, a part of me is really good at that crap.
