I need advice

Maybe I’m overreacting lol, but here’s something that’s been on my mind.

For as long as I can remember, I haven’t been able to eat large portions of food even though I love food. I’m not picky at all and I’ll try almost anything.

The thing is, I’m still a student and I don’t have a job yet, so whenever I go out to eat with my family, they always joke like, “Why even bother buying you food when you never finish it?” They usually end up getting me something anyway, but if I leave a little bit behind (which I usually save as leftovers), they’re like, “See? Told you you wouldn’t finish it.”

I get that it’s their money and they’re allowed to feel that way, and I know it’s not that deep… but it still kind of stings? I don’t want to waste food either, and it’s frustrating because I genuinely love eating it’s just that my appetite’s always been small. No idea why.

I would like advice to make me able to eat big quantities of food and enjoy it
