Crying?

Grainne • One toddler princess and another baby princess on the way 👸🏻
I know I done one the other day, but I work with elderly and in their final stages of life and I'm finding it all so hard at the minute. 
I had one gentleman tell me that he lost his daughter at the age of 13  30 years ago today from a cry for help gone wrong (suicide) and I just burst into tears and cried with him, lucky enough they knew I was pregnant and I just apologised for being in professal but him and his wife both hugged me and gave me a kiss! Since being pregnant I'm finding it so difficult not to get attached to these poor people. Maybe it's too much stress? But I am crying over everything Infact I've been crying over absolutely nothing most days. How can I over come this? And I'm sorry to drag it on its a long post xxx
