Please.. Help me?

You can do it! And yes, calorie counting does work! (It only stops working when people stop counting calories and go back to old eating habits.)

And don't stress about 'the diet' - find what works for you. For weight loss, it doesn't really matter what you eat as long as you hit your calorie goal. If you want to improve your health rather than/as well as just lose weight, adding in a few more nutrient dense foods (find some you like!) will help with that - if you need to, go slowly, one thing at a time. Also, you might find that some foods fill you up better than others, so make it easier to stick to your goal, but the important thing is you find something that works for you, doesn't make you feel deprived/miserable, and you can keep up for the indefinite future. Think of it as a way of eating not a diet. Don't be afraid to make changes to what you're doing until you find something you feel comfortable with. And if you have a bad day, or week - don't beat yourself up, just carry on, it's what you do over months or years that will make the difference, not a few slip-ups (everyone has them.) As long as on average you eat less than you burn you will lose weight.

The other two things I've found helpful are: weigh and log everything! It's amazing how wrong I was on some portion sizes, so get a small digital scale and weigh your food (honestly it's not as much of a pain as it sounds)
And don't feel you have to cut calories drastically. Try stepping down slowly to give your body a chance to get used to it; and listen to your body - if you're weak, tired and hungry all the time you probably need to eat more - less is not always better. What is best is something you feel happy on and can keep up over a long period of time.

And if you can find some kind of exercise that you can enjoy then all the better, but again, it's not essential for weight loss, so just tackle one thing at a time if you're feeling overwhelmed.

Good luck
