I have a game i want to make, but i can't

I have an idea for a game. I want to make it, but i can’t, i don’t have any skills in making games. My stomach hurts when i think about it, and i really want to do it. I am 15, which have the limits of itself. What do i do? What should i do? and how do i do it. I need something to kickstart me. Maybe a friendly advice. Thanks for reading.

I recond you to find some friends with the same interest or people who actually have the skills needed, you can also find people online who are willing to help or form teams;
If you are willing to work with games, non-unreal based, I recommend you take C++, python, lua and javascript classes (programming languages), since those are used very widespread in the gaming development comunity;
I also recomend checking for DirectX and OpenGL tutorials;
For UI Graphics and textures, I recomend someone who has at least training with photoshop and webdesign, that is, CSS and HTML;
For 3D models and such, Blender or 3D max training;
For 2D Conceptual art and such, you can use whatever software you wish, but some good ones are photoshop, paint tool sai or gimp;
For DataBase solutions, i recommend you study SQLite and MySQL (you will need a programming language like the ones i mentioned above);
For Music, you can record it or make it yourself with a computer, using software to edit/compose, such as fruitLoops, Magix Music Maker or MIDI maker;
If you are willing to work with unreal I recommend checking their youtube channel for tutorials on how to start using the engine, wiki for some nice tutorials on how to make common things, UE4 forum and answerHub for the questions you will have in the future;
If you want there are also other engines which you can give a try, such as, RPG Maker (very easy, low level engine for extreme beginners), Unity 5(High level but slightly limited in terms of AAA quality), CryEngine 3 (Powerfull for AAA development, but hard use, pro level), Game Maker (Low level, doesnt require much coding, easy for beginners too);

Most of the things i talked about can be learned on youtube, just use the keyword tutorial, also, i recommend you either start with RPG Maker or Unreal (RPG Maker has a great comunity and its very easy to use, also, already includes tons of resources for you to use), Unreal is way more powerfull, but requires a lot more thinking, and the resources arent free, you have to make your own or find people who are willing to let you use theirs for free;

There are also a lot of communities that like this that will give you lots of help
Similar to what was said already you should start taking some coding classes in languages like Java, c++, c#, javascript ect.
A really great place to start learning to code is Code Academy
If you have specific coding questions you can go to
StackOverflow
and for game design tips you can start of watching some videos at this channel

These are just some things to start you off.

I hope this helped you find somewhere to start

wrong place to post probably, but to be honest in your case unity is better for you,
its a lot easier to use, but its not as flexible.
then, when you are like 19 you will wind up in my position where unity doesn’t cut it anymore.
but its perfect for begginers to learn any concept of game dev they need to.
send me a msg if you want my help/opinion.
