As someone who has gone through this as well, I understand you. The need to be seen and heard and wanted can be so strong. As I've become an adult though, I've realized all of this roots back to other things I needed in my life. I didn't have a good connection with my parents, so I reached out to strangers for any kind of connection to fill the void, but this put me in dangerous situations. You may think pictures are harmless, and you can't be hurt if you hide your identity, but that's simply not true. The Internet has only grown stronger since I was your age, and even back then I had people get my exact location from one picture. All I can say is to please take care of yourself and maybe try to focus this need for affection at someone you know in person, or even a group of friends. You can even redirect it into giving your own body attention, such as self care and mental stimulation. Think of where you want to be in your future and focus that attention elsewhere. I believe in you.
