Having a bad birthday is a huge letdown. Acknowledging that it was a bummer and mourning a little bit is important; if you pretend you’re not upset, it can lead to a prolonged bad mood. Eat some ice cream or have a good cry, but then move on! You have some fun to plan. If your birthday didn’t go the way you wanted it to, take matters into your own hands and have a birthday redo.  Pick a day coming up (be sure to give ample time for people to plan ahead) and treat yourself to a party. Some tips for a great post-birthday bash:  Invite as many or as little people as you feel comfortable; you control the guest list! If you’re going out, pick a favorite restaurant you already love or, if you’re feeling adventurous, go to a new place you’ve been wanting to try. If you’re staying in, buy or make food and decorations to highlight the birthday theme, or consider incorporating a nontraditional theme, like a favorite era or trend, to liven it up further. Buy or make a cake to make it feel like a real birthday celebration! There’s no rule that says you can only accept gifts on your birthday, so go out and treat yourself to some gifts!  During your birthday redo, make sure to do things on that day (or week!) that you will enjoy. This won’t fix your bad birthday completely, but treating yourself can help ease the sting in the meantime.  Buy yourself a present you were hoping to get but did not. Rent a favorite movie and order takeout from your favorite restaurant. Invite some friends over or have a solo DIY spa day.

TL;DR in Indonesian:
Adakan pesta mengasihani diri yang singkat, lalu lanjutkan hidup! Adakan pesta pascaulang tahun untuk diri Anda. Manjakan diri Anda dengan benda-benda ulang tahun tambahan.
