Oh, gosh. 
Zombie did not expect to ever see a thread like this. She hardly knows what to say. She does realise that, as Worra said, some people are annoyed by her posting style. She will therefore now step out of character to answer your questions.
Once upon a time I was a relatively boring MN poster. I used to enjoy the OFRS threads and one day I thought that having a "real" zombie join them might add a new dimension. Thus IamtheZombie was born. I chose to have her post in the third person for a couple of reasons. First, it would instantly set her apart from the real people. Second, I figured that a zombie would be a bit confused as to whether she was the person she used to be or was really a zombie. Third person speak was my way of trying to show this confusion.
For several months I used my normal nickname for most of my posts and only changed to Zombie to play on relevant threads.
Then, last November, life went tits up. Actually what I mean by that is that it went tit off. I was diagnosed with an aggressive breast cancer. I had a mastectomy in November. In December I learned that although the surgery had been a complete success in that they were as sure as they could be that they had removed all the active cancer (lymph nodes clear, no vascular invasion and a clear margin around the tumours), because the tumours were so aggressive (and were hormone positive and HER2+), I would need the full spectrum of adjuvant therapies.
At this point, Zombie started to become part of my coping mechanism. She provided a harmless distraction from what was going on in RL.
I had chemotherapy from mid-January to early May. I had radiotherapy from late May to mid-June. In July I started an 18 cycle course of Herceptin which I will finish next July. I am also on Arimidex for 5 years. Arimidex can potentiate osteoporosis so I also have to take other medications to try and counter that possibility.
By late January / early February I had abandoned by other nickname and was a full time Zombie. This year I have also lost my MIL in April and more recently my Godson whose funeral I attended last week. Zombie is my lifeline at times.
As to who I am in RL... I'm 60 years old. I'm married with 2 adult DSDs. I enjoy MN for the mixture of fun and frivolity; for the serious debates that can be had; and most of all for the care and compassion that can be found here.
