eh,you shouldn't feel discouraged. always rmbr, as guys, we are extremely lucky that we have a lot of control over how we look. you may be thin now but you can always get bigger and look better. compared to thin women, who cant put on weight like we do or they risk looking weird.

p.s i've never really understood the difficulty of gaining weight. my original weight is around 70kg, but i am currently 88kg. it is basic science bro. and dedication of course. but i'd rather have to eat more and work out than to eat lest(diet) and work out.
