As @Kevin said, you’re going to have to give us something we can help you with!
I understand your frustration though, and I’m sure many of us have been there many times. What I would recommend is fully planning out your code. You already know that you have to make a game with three levels, and a main menu. You already know that you need to be able to start a game again and such. You mention that you’re not able to achieve your goal… what goal, specifically? Any section of code that you’re stuck on? We would surely love to help you out! 
If you do already have a plan, and your code is just not working out? Then again, please send where exactly the problem is, and we would love to answer it. Also, it would be best if you posted your code, so that if someone else has a similar problem to you they can see the answer on the forum and not have to ask another question themselves, if that makes sense.
Please feel free to keep us updated on your project! And feel even more free to ask as many questions as you need to, there are plenty of users here on the forum that would love to answer them!
