Ipod touch 5g won't turn on
So I've had my ipod touch 5g for about a year now and last night I was using it to watch videos and it was perfectly fine however when I woke this morning it would not turn on. This has happened before where I leave my ipod on hold and when i come back to check something it doesn't seem to respond. What I did every other time is I let the battery drain until I get the little picture that indicates that my ipod needs charging and after that it seems to work fine. My home button doesn't work anymore I've been using the assistive touch so I can't hold the power button and home at the same time. I just want to know why my ipod has been doing this so often and what i can do to fix it. I have tried to connect it to my charger and to my computer I still get no response and my ipod was left on so I know it isn't just turned off. Please help. I appreciate your help. Thank you.
