I'm sorry to be so blunt but you are a moron, denying your gecko the proper care it needs because you think everyone is pulling your leg about this being a SAND problem, you want to believe one "animal expert" over thousands of LEOPARD GECKO/REPTILE EXPERTS, this is a known fact, sand is terrible and that's exactly why your gecko is probably dead as I'm writing this, I feel so sorry for that poor animal. This is why kids shouldn't have animals... Who gets a pet without access to a vet if an emergency should take place. This makes me so angry.
IF your gecko is still alive, get him to a vet NOW. Tell your irresponsible parents to take you to the closest vet, this is not a broken dish, this is a living thing... DO NOT euthanize it yourself, as you're clearly a young person and will probably end up causing it even worse pain. After you have taken the gecko to a vet and it is healthy enough to endure a move, you need to put it up for adoption and allow a proper care taker to take over, again I'm sorry to be so blunt but all this is the truth.
YOU should not own any animal.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
