1997 Chrysler Sebring Car won't start

I went into the store I was in there for probably 20 minutes, when I came out it wouldn't start. Obviously it started vs.what I made it too the store and made a few stop before going into the store. There's power too everything else, the lights, stereo, lights on the dash and everywhere else come on. No noise or anything when I turn the key over. Tried jumping and nothing,battery cables are clean and tight and it has full tank of gas. Please help me I'ill go insane stuck in the house all winter (too cold to go anywhere without a vehicle) with two old people and a nine year old boy bouncing off the walls 24/7.......
Thank you,
