If you've come to dread your birthday. If it's become the day that just reminds you of all those you've lost. But, especially if it's become simply a reminder that it was always the day when who you weren't and perhaps who others wanted you to be, was always celebrated and never who you were. Then it's alright to simply ignore it from now on.
You don't have to celebrate it. Or at least care that it is being celebrated. Just pick another date to celebrate, a date that means far more to you now and the journey that you are on. The day your egg cracked, or you finally began to transition, as a #trans. The day you were finally diagnosed, or a time when your self-realisation became overwhelming and concrete. It doesn't really matter. Just pick a day that makes sense and make that your special day. For that day really will be about who you are and always were and you can finally have the celebration you deserve.
