Yikes, no wonder she's upset! I agree you should look for a new vet, that doesn't sound right at all to me.
Gonna restate that soaking is unnecessary and can actually be harmful to the shedding process. Instead, make sure the humidity in your enclosure is at least 60% and bump it up closer to 70% when you notice she's going into shed. You might also want to consider adding a humid hide to the enclosure. Make/buy a new well-enclosed hide (a modified tupperware container can work well here) and fill it with sphagnum moss. Keep the moss damp at all times, but not so wet that you can wring water out of it. You'll have to maintain it probably once every day or two. This will give your girl a nice high-humidity retreat to go to when she needs it.
