Oh my gosh! I used to live in Gainseville, that is so scary!!!
You can train her to go inside. I have Jaden trained to go indoors and outdoors. The easiest way to train, that I've found is by starting with the pee-pads with the pheramones in them that encourage them to pee. Confine them to a small place and put the pad out. If they don't pee on it by themselves if you are there when they start to pee just pick them up, in a gentle firm voice say "No" and put them on their pad. If you keep doing this evenetually they will get the hang of it. After you get her pad trained, what I've done with Jaden is I've moved him to a litter box. You can buy one by Purina at Petsmart and use the doggie litter they have there and to get them to start going in the box you just move the pad there. Once they realize the box is where they go you can remove the pad and just have the litter.
If you want her to walk to get exercise and can't fine someone to go with you, I'd take her to a petsmart or something like that and just make a few rounds around the whole store. Walk all the aisles and stuff, you wouldn't even have to buy anything and at least you'd be safe!
Be careful! Hugs to you and Bella!
