The lost of hope or a gate to opportunities

For a week I was fired up and bursting with ideas with my current novel. In the past few days, it's slowly going down the drain. I'm seriously stuck and currently in the stage writers like to call "writers block". I have the idea but I don't know how to put it in action. I don't know how to explain it in words. I can see it but I can't describe it through words or just by saying it. Maybe it's just that I don't have experience yet, after all I'm just a amateur who does it only because I love doing it and still debating if I should really do it as a profession. My friends recommended me to take AP literature next school year to enhance my writing skills and I really hope it works out but as of now I'm just doing it without a specific thinking of what it takes me ahead of time. I feel that it won't be good like famous writers and judging from the way things look, time is though, I'm too busy and I am not sure anymore if I should continue because of the current situation that's happening in my household. Maybe I'm just to stressed that's why the idea wont come out. I've come to the point where what my parents have told me 'it won't work out' was right. But despite this I'm still trying My best in doing what i love the most. I'm currently researching ways to improve my writing. But if anyone who has experience in writing would like to give advices I'd love to hear them, it would be an honor hear from an expert. Feel free to comment whatever you like.
