Being fearful of a dog does not indicated a good leader, which this dog needs. I've had those ''staring'' dogs and the ones that climb up reaaaaally slow and glue themselves to you. Are you practicing NILIF with her as she sounds insecure. If she's running the fence line, keep a long drag line on her so you can stop the behaviour immediately. She sounds like she just needs some structure, but I agree, if you are scared of this dog, you should return her. Nothing she's done sounds like anything that requires a euth. Rescue dogs can take months to settle in as mentioned. Some dogs are very handler sensitive so even your insecurity with her, can be feeding some of her insecure behaviours.
