Affiliate Marketing Secrets

I am feeling very confused about my attitude towards my job. I’ve been living by myself in the DC area for a little more than 3 years now. Because I am by myself, I focus a lot of my attention to work. I think that it also has a lot to do with my workaholic nature as well. Things were going well at work for the last 3 years, and then I was transferred to a new group so that I can have a more specialized niche within my group. I was transferred from oil/petroleum-product markets to the natural gas market group. This had happened while I was on vacation. (Because even though I had expressed interest in working with the gas market group, I had qualms about working with the director because he has a reputation of being a jerk at the workplace.)
The director of the group first had a great impression and high expectations of me. But after several mistakes that I’ve made, I became the laughing stock of his group. And there doesn’t seem to be much chance of a turnaround. Almost all of my responsibilities have now been shifted to another analyst that they had originally recruited. I am now under a Performance Improvement Plan, and the staff in his group (including the director himself) just don’t seem to be interested in working with me anymore after 6 weeks with the group. And there doesn’t seem to be any patience for training either (but this has always been the culture in this group. “You either get it or you don’t. We will find someone else.”)
When I was transferred to the Gas Market Group, my old group (oil/petroleum-product group) hired someone else in my place. She has 3 years less experience than I do. When it became apparent that things were not going to work out with the gas market group, the director of my old group and several senior managers basically told me that I was screwed. They told me to start looking for a new job. The director of the gas market group seems to try to work with me somewhat, but he has better things to do.
Recently, I found out that the girl hired in my old spot is only being paid $3000 less than what I am currently paid, even though I have 3 more years of experience than she does. This, on top of the fact that I had express more interest in the Gas Market Group to make myself more valuable to some managers at my old group; still being told to work weekends without any kind of compensation; and the fact that I am the laughing stock in my new group, just makes me feel really negative about my job.
I go through the days with the attitude that I just don’t care. It makes all the crap that I am going through more tolerable, and it helps me get through the day. But I don’t think that this is a helpful attitude to have, considering that I am under a Performance Improvement Plan right now.
Is there anyone out there who can tell me what I can do to get through 6-7 more months at this job? To get somethingn positive out of this whole experience?
