You have my sympathies. We recently lost a well loved 2yo girl beardie. She fell, she did eat, sort of but we took her to 2 vets and couldn't do anything for her. It hurts. You will hurt for quite a while, another beardie helped for us, but everyone is different. When you are ready, find just the right dragon for you.
Of course you're going to still miss Rascal, having other pet's helps with the pain but it doesn't take it completely away. I am so sorry for you loss, I've lost a beardie once to him eating a lightning bug, so sudden and it hurt bad. But it does get easier and you will be able to remember him someday without hurting.
I'm so sorry to hear about Rascal, my thoughts are with you
I've only had 1 beardie who is now 3 so I've never lost one but I'm dreading that day because it will break my heart. I have however just lost 1 of 4 of my cockatiels and thats hurt me really bad-but my other birds and Wicked my beardie help get me through that.
Seek comfort and put your love into the rest of your animals, I'm sure Rascal will be looking down on you all xxx R.I.P Little man
