As the others have said, it is never easy but it really helps when you can talk to others here who understand what you are going through. I know just how you feel too, I still cry lots when I think of my Georgie who I lost recently...just from looking at some pics today. You will always miss them and it's only natural to cry, doesn't matter how long after they have gone.
We smile when we think of the lovely memories we have of our little birdies, but those memories bring a tear too....usually at some point down the line, you will shed a tear and straight after, smile, when remembering something else about them
It's always a mix of emotions, we wouldn't be human if we didn't feel that way.
As Charlie said, she is probably flying around with new found friends and also looking down at you and watching you cry and nudging your cheek without you even knowing
She is always around you xxx
