It’s totally natural to feel sad when children grow up and aren’t your dear babies any more, so no, there isn’t anything wrong with you.
However, if your sadness is so extreme that it’s badly affecting your quality of life, it might be worth a visit to your GP for a check up, and to make sure that you don’t have clinical depression.
Depression can arise from many sources, not always the most obvious thing that’s on your mind, and taking some positive action always helps.
I hope everything settles down soon!
