Debbora, maybe you could check with a local shelter or children's home or with Big Brothers/Sisters to see if a child shares your birth date, or close to. (You might choose someone from the fire or police dept., EMS, or armed services or missionary/family to surprise.)
Invite friends to come to your home, each bringing a suitable small gift and have a 'birthday wrapping party' for the recipient. Provide yourselves with snacks, even cake & ice cream, balloons & candles; take pictures; have someone do a scrapbook of your event... and you'll have a truly memorable day! I hope this will work for you or give you some different ideas for celebrating your birthday. Blessings (Happy early Birthday!)
