I eat a lot

Ok so I'm 15 and I eat a lot in a day. I mean heaps. I got up this mroijg had brushetta, 3 oranges, weatbix, and a ham sanchwich in about 3-4 hours. I'm told its because I'm young and growing but I'm getting kinda worried that im eating too much. And it's not just because I'm bored, I'm genuinely hungry. I'm also on tablets for my skin and I also have put on more than 3 kg in the last couple of months.

Is this normal or weird?
