Otter Creek Override by fear

Akari could've progressed farther: her pads were only minor discomfort. But she couldn't waste all of Lane's hard work, so she threaded through the meadows at a slower pace. 

She reached the banks of a sly, tortuous creek, surrounded by thick riparian vegetation, burnt by the cold. A few meters ahead, she spotted a pair of otters playing in the water. They whistle and dive and twist with an agility that rivals the fishes themselves.

She sat for a minute, observing the creatures that behaved so carelessly, so innocently, it was odd to think those two were adults. She looked at the curative Lane had done to her pads: she managed to keep it throughout the journey, but she felt it was time to take it off. She carefully unwrapped the bands and washed away her paws in the running waters: the wound had healed fast! The bloody wounds were now a pair of rough scars.

I guess no one will praise my soft pads anymore. She smiled. That didn't bother her one bit: it was just the first sign that her life was changing. She carried other scars, invisible ones, far nastier than those.

But the signs didn't end there. For a couple of days, she had been feeling restless and blamed her wounds for it. However, the time passed, her wounds healed, and the strange feeling just kept growing.

It started with a rumbling in her stomach, then a tingling sensation started tormenting her rear, and soon a feverish state took over her body, like a fire consuming her from inside out.

She stopped more often to drink, and she thought she had gotten sick somehow. But oppositely of getting her senses dull by the disease, they actually sharpened, allowing her to perceive the world with a clarity she never had experienced before: the colors were brighter, the scents were stronger, and even the water acquired its own taste. Everything was beautiful.

In her path, she saw Blackfeather Forest to the west, a spot of woodland that somehow managed to develop in the middle of the grass fields. Ivory Rose. She remembered Lane speaking of a pack in some nearby forest. Her nose confirmed it: she felt the scent of wolves up ahead. Her lips began trembling, her tail wagging, and an urge compelling her to dive into those woods head-on.

Only then had she realized that her only affliction was to be a healthy female wolf.

I'm... in the heat?  Such realization hit her like a punch in the stomach and turned the tingling even worse.

To her eagerness adds fear. She was experiencing her first heat, and even though all her instincts compelled her to find a mate, her mind was soon haunted by foul memories of her past. She recalled the disdain with which females were treated when the heat came to them, back in Cherrywood Valley: their bodies tortured, their spirits tormented, their minds twisted into madness. Akari's could hear their screams, feel their desperation, taste their tears! 

I don't... I can't... end up like them! Her cousins, her friends... Mom...

Adrenaline spiked: Akari noticed it tainting her scent, still so sweet, so alluring. With her body shaking violently, her gaze met the forest once more, and panic took over: the wolf collapsed, panting heavily like a fish out of the water, desperately struggling to breathe.

Get out of there. Get out of there! RUN!

But her body didn't respond. Her senses started drifting, her vision blurred, and the world faded into darkness.
