Answer 1

Take XLs suggestion and find an exercise you like to stay in shape. Make the exercise something that's fun, childhood only comes once.

Answer 2

i'm no doctor, but you're still young, so there will be a lot of physical changes that will happen to you in the next few years. just remember to eat a healthy and balanced diet -- cut out the high fat junk food as that will do more harm than good. drink milk too, it's good for you.
there are also "weight gainers" protein powders that athletes use to gain muscle mass/weight available at nutrition stores -- there are pros and cons with using those powders, obviously, and may not be suitable for you.
talk to your doctor to see what he/she recommends, but personally i would say to eat healthily, make sure you drink milk, and not worry about it! :-)

you're tall and that's a superbly well-known weight for you- you're probable skinny. From what you're saying, it incredibly does seems such as you have a undertaking, or a minimum of the commencing up of one that ought to get incredibly undesirable. you may see in case you could consult with somebody and get help now, until now it gets undesirable. good success
