Thank you all so much for your words, you make me feel a little bit calm..
I started to discuss again with my mum for a budgie and she told me that I can have a new one but in my room, she cannot face a new "Sakis". I told her that I am planning to call my new budgie (when I'll have it) "Charlie". I have to go with my brother to Sakis' breeder, to see if I can find a relative of him..

That sounds like a great thing to do hun, you will always hold a place in your heart for sweet Sakis, but a new budgie will let you love again and will give you lots of enjoyment. Cant wait to see pics when you get your new sweety
