won't turn on. pitch black screen

I was at school during lunch my iPod went to 20% so I left it alone. Then, when I got to study hall to check the time it wouldn't show the lock screen after I already clicked the lock button. So I thought it was already died during study hall but when I got home to plug it in, it wouldn't turn on. So I went in my moms room and plugged it into her Mac and it still wouldn't turn on, also I tried holding the lock and home button(my home button is broken) and still nothing. I also tried just holding the lock button but that didn't work either. So I'm getting worried, I tried pulling up iTunes and it isn't connecting to iTunes, I tried just letting it sit and charge for an hour and literally it's not working. But it was working perfectly fine at school and when I woke up this morning, so idk what to do honestly I tried everything, I looked up so many things to fix it and nothing helped me out because it involved using my home button, which doesn't work because its jammed. And I truly believe that I don't need a new iPod, its in great condition it just goes pitch black at times and I usually fix it by connecting to my Mom's computer/iTunes. I just need some help, I really don't wanna call the Apple Store.
