Metabolism Jokes

I am currently about 125lbs and 5’9″ tall but I would like to gain about 20 more lbs. Can someone help me??
Im 19 years old and I have very high metabolism but i wouldnt mind being a little bigger by 20lbs or more. I wear I believe a size 3 in jeans. I’ve battled the ‘anorexia’ jokes and comments since the 6th grade and it made my self-esteem extremely low. Ive been to website that say my weight is a healthy weight so they give me no advice. I’ve also read about the whole ‘count your calories’ thing and all that did was confuse the mess outta me so im asking if someone out there can give me advice i’d actually understand or suggestions of foods to eat…ANYTHING. Im really desperate so thank you in advance for taking the time out to help me.
you are lucky cause you weigh 125lbs my weight is 245lbs and I’m 5’9 tall and I would love to lose a couple of pounds.
