Why doesn't my body want food?

I don't know whats going on.
Ever since the day before Christmas my body hasn't wanted me to eat. I haven't been feeling hungry and when I smell or see food my stomach turns. I've been forcing myself to eat atleast once a day and when I do, I feel sick...

to my stomach (but I don't throw up or anything). In the past two months, I've had two bladder infections. I have no idea whats going on, but I hate it. I want to eat, my parents cook nice meals almost every night and I don't even eat any. My body is fine with me drinking liquids, not having a problem with that yet, I am always drinking lots of water.
Does anybody know whats going on? I've never had eating problems in my life.
I don't do drugs, drink, or smoke (if that could have anything to do with it, I don't know, just throwing it out there)
I will make a doctors appointment but he is always booked up for like atleast 2 weeks so I don't know what I can do to help myself till I can get in to see him.

first of all I know this is personal, but are you having normal bowel movements? Anytime you have a change in appetite or stomach problems and it continues you need to see a doctor right away. If your doctor is booked go to an am/pm clinic or one that doesn't require an appointment, make sure you take a preg test and if neg insist that they do an x-ray, if there is a problem they can get you into a specialist or admitted to a hospital right away. This could be serious, never just let things go that is one way many many people each year end up in major surgery and with colostomy bags, trust me I have taken care of several of them. I am not trying to scare you be this is needs to be taken serious.

Try drinking cran-peach juice for your bladder it tastes good and good for you. . . Has anything been stressing you out ? Try eating ordrinking some broth with some crackers, light and hopefully won't irritate your stomach. Try some Tums when your stomache hurts that may help a little you may have an ulcer? Tums have calcium too good for the bones and teeth. . .

No, I don't think I'm stressed out, not that I know of.
But sometimes people don't even realize they are stressed so I very-well could be.

I met and 12 year old whose body wouldn't let her eat. Wait did you go to the doctors they can help...

Your body may just be changing it's cycle, you know what I mean. . . Make sure you do eat small portions, also try drinking slim-fast or ensure they have they daily blah,blah blah's your supposed to have. . .That way your not cheating your body from nurishment it needs to grow healthy. . .
