Dog on the market

Luna just turned 3 years old recently. She weighs about 10-15 pounds. Her hair grows really long, so I do my best to keep up on her grooming appointments. Luna is Brown and white, mostly brown. Luna is a very loving dog; she wouldn't hurt a fly. However, she is very anxious. She takes a while to warm up to people and she is always jumpy. I bought this dog from some Amish people when she was around 5 months, and she has been like this ever since. I really want her to go to a home with people who are a little more patient and can make time to give her attention. I originally bought Luna because I was looking for a new emotional support animal due to my anxiety being super high all the time, but Luna is just a little too nervous and anxious all the time to the point it sometimes triggers my anxiety way more. She needs the same type of support as me emotionally and I just can't give that to her right now because I haven't mastered it on my own yet. I hoped maybe after time went by she would come out of that anxious or nervous state, but she hasn't yet, and I don't want to get upset with her. I'm looking for her to go to a nice new home who treats her with love all the time and who could maybe break her out of these anxious habits. Luna is not fixed, she has had some shots, and has been checked into a vent for appointments, I do have her paperwork to show for as well. Luna is great around anybody honestly; she is more nervous of people than they are of her and she is potty trained. Please help me welcome her into a nice loving home. She is a amazing dog and loving she just needs a little extra help emotionally, im not sure if when she was a puppy if something has happened with her while living more up north with the amish and thats why she is so shaken up, but she shows alot of different signs of physical communication that makes you believe she has been through something and thats why she is always so up tight.
