Lisa, I've been watching this thread from the start, but waited to comment since honestly, it hit home for me. You found the forum while seeking like minded folks who understand the bonds with our parrots, and how we feel when we lose them. I'm so sorry you had to find us under such heartbreaking circumstances, but we're glad you're here. You found what you're looking for. So many of us have been there. We truly understand.
Now, the thing that struck me at first was your Alex being only 8 months. Far too short a life for such a beautiful little soul. You had birds previously, but for you, Alex was the one. That special, indescribable bond that feels like never before, and you'll never have again. I have also had other birds, for many years in fact, but never really understood that connection until I met my boy Patches, my first Ekkie. He was my "one." He had the saddest life, and after all that for 18 years, he found me, and got his forever home where he knew how much he was loved. Unfortunately, too much damage had already been done, and he passed in my arms after only 8 months, right before Christmas 2018.
So, yeah, that bond is real. It's unique, and strong, and earth shattering when it's ripped away from you. It's okay to grieve, and you should. I still have bad days when something reminds me.
Everyone is different, so the grieving process is very different from one person to the next. Only you know what that looks like for you, and that's okay.
For me, I chose to open my heart and home to another bird, to honor Patches, and help another bird in need. It was something I needed to do for me. That's where my guy Tucker comes in. (another Ekkie) Aaaaaannnd, in the process of adopting him, my girl Baxter, my YNA, found me, and sucked me in too. I'm so blessed to have them both. I can't imagine life without them now. They'll never be Patches, but that's okay. They're unique individuals, and while completely different, the bonds are just as strong.
I'm not saying go out and get another bird right now. AT ALL. Just saying if it's in the cards at some point, your heart will know when it's ready. Don't rush what your heart needs.
Again, my sincere condolences. Alex was beautiful, and will be missed.
