Ferret needs euthanasia

I figured this would get more views if I posted here. It's kind of urgent.

So, of all people, you would think i'd be the last person to be posting for advice on this topic, given my title. However, when it comes to my own animals, I become that little girl who knows nothing medically past picking up poop with the pooper scooper.

I have a ferret who is 8 years old. Never been tested for adrenal gland disease, but has always had the alopecia (hair loss) around the tail-rear end of his body. He's always been a ferocious eater. These past two weeks he's lost his appetite, lost the ability to control his bowels and urination, and has seizures. Yesterday and today he has trouble standing on his back legs, and "swims" around when he's put on the floor. Currently, I am giving him Prednisone twice daily and force feeding him...however, my heart and my gut tell me he's suffering. I think the best gift I could give him right now could be euthanasia. I feel like i'm making him suffer and I can't let go.

Does anybody in Florida know of any good small mammal vets? I'm embarrased to bring him to the vet he saw 2 years ago, considering the condition he's in. I never let my animals get this bad, however, Harley has.

These past few months have been really tough for me. If it weren't for you guys, i'm not sure if i'd even be around right now.

Thanks for listening to my bulls**t.

While I don't know of any vets in your area, please hear me out on this:
Don't let your ferret suffer because YOU are embarrassed. I am sure the vet he saw before can understand how hard it can be for some people to 'let go' of a beloved pet even when they know they should.
Please, swallow your pride/embarrassment and take the poor boy back to the vet if you haven't found a different one by now!
My heart goes out to you because I've been there...
