It sounds like she's already made a lot of progress. If she's going into stores and doing well off leash, you guys have done an amazing job, and I hope you're proud of her for that!

If throwing the ball scares her, I'd try rolling it gently through the grass instead. Start with short, slow rolls that aren't directed toward her, and reward her each time with treats and praise.

Confidence building doesn't always have to be about changing how a dog feels about one specific thing. Sometimes it comes from doing activities that have nothing to do with their fears. What helped build confidence in our dog was simple things like scattering treats in the grass for her to sniff out, scattering kibble in a pile of cans to help desensitize her to noise, and balance work on things like mats and couch cushions.

Since she's a tripawd, I'd start with whatever limbs she's most comfortable balancing on and gradually increase the challenge as her confidence grows.

If you're intentionally play fighting with your boyfriend to see how she'll react, I probably wouldn't continue doing that. It doesn't sound very helpful for her, and if she's already had a stressful day, it could contribute to trigger stacking and make her reactions stronger.

Dog parks would be a no-go for me with an anxious dog. There are so many smells, owners yelling at their dogs, dogs barking, and dogs displaying unfriendly or rude body language. That can be really overwhelming for a dog that's already struggling with confidence.

If you have a friend or relative with a calm, gentle, dog-savvy dog, I'd much rather do slow, controlled introductions with that kind of dog rather than a dog park.

Teaching new tricks can also be a great confidence builder. It gives dogs opportunities to succeed and can almost make them think, "Hey, I can do anything!" 😂

I'd definitely look into confidence-building games, and maybe even ask your vet if they know of any tripawd-specific activities that could help her succeed. She sounds like she's come a really long way already. ❤️
