Advice needed please

So basically I don't eat meat, I dont believe in it and I feel that its wrong(just my opinion). But my entire family disagrees with me and sees no reason why I shouldn't eat meat.

The problem is that I still live with my parents(I'm only 14) and my mom only cooks meals with meat, so I just dont eat the meat and eat the rest. But now I feel as if I'm iron deficient, because I guess the meat is the only iron source in the meal. I'm always tired, dizzy and lightheaded, especially on my period.

I obviously cant move out now, but I have made plans to move out when I'm 17, since I graduate high school when I turn 17.

Can anyone give me ideas or advice to deal with this.

Thanks xx
