But now im so determined that i want to lose weight fast
Right off the bat, scratch that idea. You don't want to lose weight fast, you want to build the habits that will have you eating right and looking the way you want the rest of your life. You didn't get to the weight you are now in 3 months, so losing it in 3 months isn't necessary. Heres my overall diet idea - Learn to eat right. the following is mostly cut + paste
you have habits, and you need to shed old ones and create new ones. If you want this to really work, you need to make the changes in your life over time so that each one becomes a new habit and each one becomes a part of how you will live the rest of your life. You aren't going on a diet, you are changing the way you eat.
You needs to forget about "dieting" and instead learn how to eat. You can't view what you are doing as a phase or something you'll stop once she reaches x goal, it has to be a change of life. Otherwise, when you hit that goal you won't have learned to eat a way you enjoy, and will very likely go back to eating poorly and gain weight back.
All you really needs to do is eat less than what your maintenance is, and over time you'll get there. You should target either one meal or one of your weak food points every 3-4 weeks to change, and the same with exercises. That gives you enough time to have adjusted to the last change and have it feel like a normal part of life. If you wants faster results, remind yourself of how long it took you to get to that size. If it takes you 18 months to get down to 120 from 145 you are at now, so what? You'll hit 120 at a diet and exercise level that you can keep up the rest of your life and be happy with.
here is some referential stuff to think about, or pick up this book. They have it and some of the variations on it at Sams Club even
I feel like I've posted this a thousand times but here it goes again
So do you eat the muffin normally and then eat a ton of other stuff as well? or do you eat 1/3 of the pile of fruit and save the rest for later?
Do you have the tart for 440 cals or just one bowl of the raspberries for 55 cals?
Do you end up eating all the things on the left side, instead of the meal on the right side that ends up being 1/3 the calories?

So for now, think about a day of how you ate before you started this diet. Think about how you'd like to eat. And then start thinking about how you can eat in a way you can sustain over the next 60+ years of your life while looking the way you want to look
