Hello there Honey! I know exactly what you are going through!!
I have had many different pets over the years, and I've loved them all, from the smallest to the largest to the slimiest!!
They give us unconditional love and affection regardless of what they are, plus hours of enjoyment. We can tell them our innermost secrets and they don't answer back or try to judge us....and don't care what we look like in the mornings!!
I am very sorry to hear your hamster isn't well, and understand how worried you must be. Sadly it is a fact of life, and one of the drawbacks of owning a pet, that undoubtedly they will leave us all too soon...the time is never right.
I truly hope that he will recover, but if the worst happens, although it may feel like some small consolation at the time, know that you have given him/her a good life and the best chance you could.
Ignore what others may say about "it's only an animal!" .....thats utter rubbish!! Those people have no idea what they are missing out on in life!! YOU feel how you want to feel, for however long!! There are no set rules, and no-one has the right to dictate that to you. 'To feel' shows you are a warm loving person and should be respected for that.
Take Care...I am here for you if you need to talk ok??!!
