why dont I gain

If you want good mass, not fat mass on you, eat more protein (meat meat meat meat, and milk are good sources. Also, try oats for breakfast) and work out. Don’t worry about running or doing any cardiovascular workouts.

if you want fuller boobs and butt then eat peanuts and parsley and yuca

try to strech your apetite like add just a tiny bit more to each meal

I was skinny, a lot like you actually (except im a guy) for my whole life Until sorta 16 ish.

I got severe depression, (had me in hospital numerous times) got lazy and started eating nothing but crap.

I can tell you the unhealthy way to go… Eating NOTHING at breakfast, this puts your body into starvation mode, storing every bit of fat it can, then at lunch eat LOTS of sugar… not just a candy bar, but like half a tub of melted ice cream. Do NOT excersize.

Heatlthy way is typical, eat good foods, excersize.

Because you oviously dont have a huge appetite, trybhaving 5 slightly smaller meals aday.
