Doubtful: Your question is very concerning. You're a diabetic, you state you are sad, and you're just reported loss of smell and taste. These need to be worked up. Is it you antidepressant medication? This is infamous. Do you have nasal polyps? Easy to fix. If you are also B12 deficient, this is extremely serious and needs to be worked up and addressed. But it's probably not the cause.
