Recently, my family have been rather suspicious of my change in eating habits.
I refuse to eat unless it is a certain time of day (a ten minute window between 12:40 and 12:50, and another between 6:00 and 6:10 pm.
i refuse to eat unless i am in a certain mood. i only eat when happy, which is a problem as i suffer from depression.
i only eat when completely alone. if anybody, even family, is or are around me, i refuse the meal.
Am i just fussy or am i anorexic?

You are displaying signs of OCD and when that surrounds food it can often lead to anorexia.
I can understand what you mean-I used to have quirks about food, like having to chop things up into tiny portions or drinking hot water with oxo in it to fill myself up...anyways-your eating habits sounds like you are subconciously/consciously trying to give excuses for not eating.
I sought out help and have now thankfully gotten over my quirks as I was worried they could develop; I still have a fear of getting fat, but I've accepted now that you only live once and I didn't want to ruin that by denying myself something I wanted.
Please seek help, just as a precaution, these things can start off small.
Good luck, and if you need any advice, just ask :)
However, i love eating when i'm at home.
Ignore the people on here telling you that you are annoying or whatever, what you have is a health problem, it's like telling someone they are annoying for having cancer. It's not your fault and you can get over this :)
Anorexia is where it's psychological and you're afraid of being fat or overweight, so you starve yourself.
