am i eating enough 5 month pregnant ?

My mother is continually telling me to eat for 2.Because of what I eat ( i’m still some nauseous and cannot eat much honestly and what I eat is mostly sandwiches, fruits,dairy,pasta,bread,eggs,pizza) she is telling me the baby is starving and cannot have enough nutrients because of me.

She implies to eat cooked food 3/times a day and I’m starting to feel bad i’m not eating healthier for the baby.I tried cooking some rice and chicken yesterday but ended up eating only the rice cause the chicken smells made my nauseous 😖.

I’m starting thinking am I eating that bad? I’m taking my prenatal vitamins but are those and what I eat enough? I don’t know who to believe i’m beginning to break down everytime she calls me she asks about what i ate and judge me.
