Living with non Seekers

Thank you for listening.
PROBLEM:
I ve been living with family since starting my sadhana.
i have to say that living with people that do not follow the path is hard.
Especially when it come to food. now as much as i respect them we have been eating meat since i can remember, but now i do not eat it, and i know that i can not force others to live like i live, this is why i plan to move out  this summer.
My mother and stepfather cultural conditioning is very strong, so it's almost like a sacrilege to go my own way. But the call is too strong.
Sometime i eat meat to make her happy, and if i don't eat her food she get frustrated, she think meditation is something i do for fun, in my sparetime. It's becoming hard for me to meditate. And family is coming to visit this summer and i don't even think i'll be able to sit for 10 min.

SADHANA:
My meditation is going fine, at first some evil spirit use to come and prevent me to meditate but i noticed that if i ground myself by working and praying everything become fine.
Also i was able to get in a very deep state of meditation.

Question:
Please i want your opînion on this.
i know that what i am doing is egoististic but how can i progress in my sadhana without going away from them?The benefit of Sadhana is immense but i do not care about those benefits because even them do not meke me happy, i seek God alone.
my room is always full of the smell of meat and passionate music that my sister is listening to.
i don't hate them
