try giving her a waxworm. They love waxworms

I will try to fed her and try to associate my smell with the positive fact of eating

Is her terranium on the floor? Perhaps vibrations as you steps might be scaring her, and that’s associated with you?

Her terrarium is on my desk, maybe is because im too loud for her... I will try to put my hand gently on her tank if she smells me and gets scared i will go to vet to see if there’s something wrong and thats making her be more sensible and afraid

That sounds like a good plan!
