What is happening with me?

I'm not sure whats wrong with me or maybe im just over-reacting.
I am never hungry at breakfast [which I think is the most important meal to have], and I cant force myself to eat it because I feel really full, and by the time lunch comes, im not hungry too and I cant even finish a fruit juice, and when its time for dinner, I eat very little. This happens for a few days and then suddenly I get really hungry for a few days. I recently went on a holiday to stay at a relatives house and I weighed myself in the doctors clinic [my aunt has a bad wound and has to get it checked everyday] and I weighed 105 pounds. I then ate a lot of food [not really junk, just more than usual for breakfast, lunch and dinner] and then the next day I weighed myself again in the doctors clinic and I weighed 100 pounds. my eating patterns have been changing weirdly since then. Is this something to do with me going throught puberty?
Also, all my friends say im really skinny, but my mom and I think I'm more on the fatter side. I'm 14, approx. 5'6 and I weigh approx. 105pounds. my mom couldn't beleive I weighed so much.. but is that really heavy for my age? My bones are on the smaller side...
What is happening with me?

OMG you r NOT HEAVY at ALL!!! if anything, you r too skinny. I am 13, and weigh 107 and im only 5'1'!!! you should try to eat small amounts of food all through oout the day. you r VRY skinny. you should try to eat more.

no you are not heavy at all...that is the normal weight for most girls around that age. so just wouldnt worry about it.

ok any chance you have an eating disorder? it could be your not eating enough.and no you r not fat I am 5 2 and a half and weigh 105 and I have thick bones. if your fat, then im a cow. try gradually eating mroe and working yourself up good luck!

Don't worry about it. Just eat when you're hungry. Despite what most people want you to believe, there's no such thing as a 'normal' weight. I've known 6 foot tall macho men who were elite soldiers in the military (Seals, SF, etc.) and only weighed about 95 pounds. They were totally healthy. I've known 5 foot tall girls that weighed over 230 pounds without a speck of fat anywhere on her body. She was totally healthy too. If you're a girl, when people are talking to you about your weight, remember that jealousy RULES. As long as you feel good, and take good care of yourself, you're fine. Being skinny isn't a crime, and don't let jealous people try to convince you it is. I've been to countries where every girl I met was around 5 foot 6 inches, and about 90 pounds. Not a single one of them had any kind of eating disorder. They were all normal, healthy girls. I met tourists from the USA that were ANGRY that the country was full of skinny girls! Weird!

this may sound stupid, but what's a 105 pounds in stone?

hey I'm 14 and I'm 4'11 and I weigh 107!!! you're very skinny, believe me!!! my stomach is skinny, but my thies are- huge!!! so don't worry about yourself, your not fat at all! you're even UNDERWEIGHT!!! you're soo skinny I'm jealous!!! :'(

o.k I'm not 107.... I'm less.
but that doesn't matter because you're underweight!!! and I'm going to be 14 only in August.. and I'm short!!!

hey! im about your age and I and 5' 6 1/2' and I weight 140!!! there is no weight you are over weight. ignore your mom. what you should try to do is stay active by doing a sport or running or really anthing and maybe that will make you more hungry. try to have breakfast and like and afternoon meal so that when you wake up your not full from your night diner. : )

im 14, about 5'11 and 90 lbs. im very athletic so I have to drink a lot of water. my mom ends up watching what I eat to make sure that I get enough. honey, your not fat. and yeah, it sounds like your eating has changed. I've never been a big eater so im waiting for when I CHANGE! lol. I want to like food more! your mom, believe it or not, have no clue what shes talking about right now. if you want her to realize that you not overweight then next time you go to the doctor, talk about it infront of her. she'll hopefully understand.
