I don't know where to go…

This is my first time playing platinum and I feel kinda stupid asking this but can somebody tell me where I need to go next. I have tried going to sunnyshore city but that was blocked off and i searched up why and it said i needed eight gym badges. Then I tried going to Snowpoint city through the cave on route 211 but I needed push which I haven't found yet. I then tried going to snowpoint city again through route 210 but it was blocked off by a bunch of psyduck, I searched up how to move it and it said I need to go to pastoria city and receive medicine from Cynthia but it's blocked by news reporters. Please I need help because i have loved playing this game but i have been just running around trying to get to a new gym but its just become really boring so if someone can help i would be thankful because google has not helped me at all.
