I'm so sorry to hear this...
It's truly devastating to lose such a beloved and special little friend, you have my deepest sympathies.
I know the pain you are feeling right now is hard to bare, but as time passes by the hole you have in your heart left by your Morgan's departure will heal and soon be filled with all the happy memories you have of the good times you spent together. Your precious budgie boy will forever live in your heart.
Rest in peace, little Morgan. You were much loved and will be missed.
Despite the very sad circumstances, welcome to the forums. I hope you will start to feel better soon. Take care.
