Okay - it sounds like I wrote your original post. Now I'm not saying you love or hate your job, but I will give you a word of caution. I've found it with myself and others that have been diagnosed with BP that it is very easy to run from their current situation by constantly making changes in their life - new job, or a move, etc.
I was diagnosed last year and once I started feeling more normal, I questioned if I wanted to live in my current city... or was my job right for me? I wanted to change anything and everything I could, thinking that it would also help in making me "better". (granted, some things in your life probably have changed for the better) I have had the same job for the past 4 years and up until mid-last year, I loved it. But this year has been very different. It's taken me a while to realize that my dissatisfaction with my job stemmed more so from lack of self-confidence after being diagnosed. I mean, you spend 31 years thinking you know yourself and then BAM! you get hit with this news. Granted it was great finally understanding what was wrong, but it does change you and the way you view things.
I didn't feel confident in myself to work with my customers and it resulted in me basically hiding out in my house and avoiding my customers as much as possible. And when I was with my customers, I wasn't trying to sell anything. They were just "casual" calls.
I guess my whole point is to say that it may not be so much your job that you're hating, but just the realization of this illness and how it is going to effect your whole life that is complicating everything. Is it possible for you to take a leave of abscence (medical or personal) so that you can have more time to focus on yourself? I took 4 weeks off when I was originally diagnosed. I wish I had taken more time for myself. It's easy to start feeling a little better and then jump back into your old life. But it may have just been too soon. If you can't take any time off, then maybe you can find other aspects of your job that you do enjoy and focus primarily on that, or relate your job to your greater purpose. For example, I've been able to enjoy my job again by focusing on the end result and what that will mean for me... if I'm out there working and succeeding it makes me feel good about myself, I'll be making great money, and that can lead to my ultimate goal of starting my own business b/c I'll have built a good nest egg for myself.
I'm sorry that this is so long of a reply, but I can very much relate to where you are at this time. Best of luck to you!
