Dear, why are you so bothered by it? I think, as a Muslim, I shouldn't care as for what other people are doing in their lives. Yes I am fasting and consideration is appreciated but in reality, they think you are insane for fasting in the first place. When you are in the US or any other Non-Muslim country, everyone is eating around you. No one will care for what you believe in. I think you should look at the wider picture and accept this as jihad ilnaf and inshallah you will be rewarded for your practices.
