12 more lbs to loose!!! i need some motivation.

So my starting weight a few months ago was 138 lbs. i went on a diet and i got to 135 lbs. then i stopped dieting...im sure you know how it all is! You "fall out" of your diet plan. So i started back up again and picked up from 135 lbs. I'm now down to 127 lbs (im 20 years old 5'3) So total- lost 11 lbs. Sounds amazing to me...but its not.

i dont see ANY results! i still feel like the fat old me. Like my pants are starting to get a tich loose and when i was a size 7 before, i'm  now a 5. I'm loosing weight in places i dont need to loose weight. I had puney little arms to begin with and now my arms are like the size of a fricken pencil! (okay not really) but i'm doing 30-45 minutes cardio EVERYDAY! i do ab workout EVERYDAY! and let me tell you...INTENSE! Ab workout. i'm not loosing weight in my belly or my thighs or my butt...its still flab. I lost it in my chest area (tell me, what girl WANTS to loose her chest?) my arms and my face.

ugh its so frustrating because i still have this friggen muffin tops and my belly still hangs over my jeans and i'm still a size 5 and im getting so frustrated. part of me just wants to give up and say i wasnt meant to be thin! (im very small bone frame) Does anyone have any advice???? i got out of the shower today and im liek HOLY CRAP!!! ITS STILL THERE. Of course i am on my period right now, so i tend to bloat out a little when i have my period but that does not give an excuse for the fact i'm not loosing it where i need to loose it. I've contemplated going on diet pills (which is NOT like me to even think that) i've been eating 1,200-1,300 cals per day) i used to eat like 1500 or so but iw asnt loosing squat so i cut it down a little and thats when i started loosing some, just in the wrong places. I have 12 lbs to go and i dont WANT to give up but i'm loosing all hope for this. its so frustrating.....i've tried even doing arm workouts to make my arms bigger but they just keep shrinking!!! those long sleeve shirts are like tight around my belly but sag on my arms. I'm not even joking or exaggerating when i say i have the arms of an anorexic....Everyone points them out and i try so hard but im like really...do you need to make this diet any more hard on me?!?! i want to loose it in the friggen belly.

uuuuugh im so frustrated and just want to throw the whole thing away. I've NEVER  made it this far before so i dont really want to, but i do.

tips? motivation?

Also i wanted to add:

is it normal to feel like you failed yourself everytime you eat?!? Like i could eat an apple and i will be like "oh crap, i shouldnt have done that." like i DO EAT!!! dont get me wrong. i'm eating VERY VERY healthy and eating exactly what im supposed to, but i like hate myself everytime i do eat.  i am aware that i need to eat, so i'm not and i will not go anorexic and stop eating.

For your activity level you aren't eating enough.  And feeling guilty for eating an apple sounds like you are getting scarily close to an eating disorder.

I think you should slowly start eating more, plan ahead so that you are eating enough and that you are eating healthy and that you don't need to feel guilty because you aren't over eating, and make sure that your deficit is about 500-800 calories a day.

You're probably not losing fat because your body is holding on to everything it's got in case you start eating even less.

And also, pants sizes are just numbers, so if your belly hangs out of whatever size you're wearing, there is no shame in going a size up and having any part the is loose (bum or thighs or whatever) tailored.  No one else knows what sze they are and you will look thinner when your clothes fit properly.
