I have faced that questions many times in the past. I faced that twice tonight. One, I made up my mind using skills I have been learning as a First Responder. The other, I have yet to make up my mind.
In the first, Hannah fell six feet from a tree stand/tree house and got hurt. She was crying a lot (obviously) and bleeding a lot. Looking her over, the blood came from a scalp laceration which means there is a lot of blood by nature. Her arms also hurt, but there are no breaks. Sore to the touch, but she still has grip. She is favoring it, but a wrap to give it extra support while she sleeps brought immediate smiles. Her head has a gauze on it and it is wrapped. Keeping it in place while she sleeps will be a bit more difficult. There are no obvious signs of a concussion and she is in bed with us tonight to keep an eye on her. So, we decided to not go to the ER unless things change. Having the emergency radio, Doc's number in my phone, my medical bag, and (if necessary) a drive directly to the ambulance bay if I feel the equipment on the ambulance is needed.
The other is more complex and less direct. I found my other two children on facebook. One has an open page, the other is locked down much like mine is. Do I contact them? Do I let them know I found them? Do I tell them who I am? My immediate response is YES! But I am not the one who raised them. Who knows what their view of me is. Would contacting them cause them harm? Would not contacting them and them finding out later that I did have a way to finally contact them cause them harm? They can not find me on facebook even if they wanted to. (Although there are plenty of other ways to find me. I do not want to hurt them. I also want to make sure that I am not being selfish. I want to contact them and hug them and find out all about them. I am also afraid. I admit it. So is my desire to contact them, yet being hesitant born out of selfishness? I don't know.
