Dragon with stress marks

[Mobalized]

So my girl that i have had now for only two weeks has terrible stress marks very dark under side with marks all over. She is about 3.5 months to 4 months old, about 7 inches from nose to tail. She unfortunately is only in a 10 gallon tank, but will be in a 40 breeder this weekend. She gets as much fresh greens as she can eat a day, kale, romaine, zucchini, and kiwi. She gets crickets only around 15 a day. Her temps are 78 on the cool end and 100 in her basking area, she has a log she can get closer to the lamp if she wants which is about 115 at the top. When i put her in the tank she gets dark and very bright stress marks, when she is out of her tank to be fed or just run around on the floor she doesnt have them for a while but if you mess with her at all when shes out and about they come back. All she wants to do is curl up somewhere dark under a couch or against a corner in her tank. Any ideas?
