I get no advice or guidance from my supervisor
Several things come to mind:

First, know that this is frustrating for many PhD students and it is normal for people to feel anxious if they aren't on a set course for their dissertation at the end of year 1.

Second, is it possible that your advisor is not a great match for you? My dissertation chair was not an expert at all in my dissertation topic (no one in my program was), but he was an accomplished scholar who could help me develop skills in identifying appropriate literature and narrowing down a topic. You may want to consider if someone else in your program is a better fit and switch advisors. This happens sometimes. It's normal.

Third, this is why PhD programs have students assemble dissertation committees, rather than just work with one person. If switching advisors is not an option, find someone else in the area you want to research and meet with him or her. Invite him or her to coffee or lunch. If they are at a distance, ask them to talk on the phone. Many researchers would be flattered that you are interested in their area and want to pick their brain. This may help. 

Finally, does the literature indicate that there are specific topics in this larger area that need to be explored? Maybe you are not consulting with the right literature or there is a lot more out there to consult with. 

Hope this helps! Good luck!
