That must have been a shocking & scary moment indeed and yes, it could have been worse, especially on a bridge, but you're safe
If still having any physical pain after a few days then think about seeing a doctor, it might just be only a result from the very stressful moment but you could have twisted some muscles as well, and since it happened during work, it's your right to claim to see a doctor and take a break if you think you need it.
Deep & intimate connections between mother & child never go away, at least for those having the chance to grow up and live with good parents, unfortunately that's not the case for many children in this world. Therefore it's something to cherish when you had that chance and it's a very positive thing to keep & feel that protective connection.
Music has always been important to me, in both happy & sad times, in fact I do think that it's the most emotional form of art and the easiest one to connect with, it can make you laugh or cry quite easily and some songs have got real healing power. I'm no doctor but my prescription would be those 2 tracks.

At first I thought I'd reply via private message, but well, we're all human beings after all and it's sometime important to have real human conversation in this crazy connected world
