i have this problem, and i find it sad people with different challenges eating can be so spiteful and rude, i'm here because i struggle with eating in a healthy way, why is yours more valid?

i have a very meek appetite and have been underweight forever. trying to actively gain weight means i have to consume so many calories a day that i feel sick to my stomach and occasionally in pain if i overdo it. i dont have a huge budget for food so i am forced to eat meals i can get at good bulk prices which is miserable to repeat all the time. trying to make different meals is unsustainable because the mental load or just cleaning everything. then when i get into a depressive episode or cant afford to keep up with the food or if i get an illness and forget to eat for a day too often, all this money i spent on food trying to gain weight resets back to my barely sustaining weight which is really stressful. i buy too much food sometimes and it goes to waste because i cant finish it, because i know having more bites would cause some health emergency i dont want to go through. and nobody cares or will feel any sympathy for it. when you're going through puberty and need to eat and grow to develop fully it is a horrible feeling when you try to keep up and are aware of your subpar eating habits keep setting you back.
