need to rant

I am feeling really pissed off, I have made a Mei tai carrier to sell, I have called it a Palmsupial... that's not the problem,. the problem is that a woman I went to school with saw them on my business page, made one and is now selling them too...

I don't know whether to approach her about it, or to just leave it, anyway it makes me unhappy and I have been careful not to sell/make things that my friends are making, I have tried to keep away from that as I feel its unethical.

I am able to make most things I see yet I don't as I respect the creators rights on it. I understand that most clothing ideas come from someone else etc, nothing is new, its just frustrating me as I am making these to sell and shes copied my idea and doing it too....
