1987 Honda Accord Won't start, won't even turn over

I just got my car back after allowing someone to borrow it for a while and when I got it back the car would not start with the key however I could get it to start by push starting it. On my way home however, the car died while I was driving. I couldn't get it to even push start now and none of my interior warning lights will work. My exterior lights will work so I don't think it is the battery. I think the starter is out which I am going to go get tested but is there anything else that could be wrong because something more seems to be wrong since it just died and won't even push start. What else should I look at to replace/fix?
