Thanks to Everyone for your replies.
After reading that it might have a virus, I stuck it out on my front porch for a day. It seemed to do better, and I thought it might like more sun. So I put it out in the yard by my flower bed.
We got a huge rain storm on friday and I was gone most of Sat, so this morning I went out to take a look and it seemed happier. I stuck it in the ground right next to where the pot was sitting.
We saw some plants at the store that looked similar and decided we think it is an Impatient too. Hopefully, after my abuse and the poor thing loosing most of its leaves, it will bounce back.
Thanks for your help!
