Do I have a bad nose job? A little over 6 months post op and I feel like my nose is ruined.

Hello, and thank you for your question. 
I'm sorry you feel this way about your nose, but I assure you it is not ruined. The dorsal hump looks great and the tip was nicely defined. 
However, it has only been 6 months. Postoperatively, after a rhinoplasty, you can anticipate bruising and swelling that is noticeable to others for 1-2 weeks. Sutures are removed at 1 week along with any internal or external splints. You will notice that your own nose is swollen for another 2-3 months. Final healing time can take up to 1 year. So, it is possible your nose has not finished healing. 
Talk to your physician if more concerns begin to arise in the future.

You may not like your nose but it is not "ruined". Based solely on these pictures I feel you have a nice result and would not recommend a revision. I think you have a much more attractive feminine appearance. We repeatedly say that it takes a year for a nose to totally heal; I suggest you be patient at this time.
