I am a first-year PhD program at a certain top-10 graduate school in my field on the East Coast. I wish to transfer to a certain top-10 graduate school in my field on the West Coast.
I have been dealing with health issues that have made living a normal life in addition to carrying out my academic duties quite difficult. While I haven't allowed it to affect my performance at all, my life has become a living hell. I wish to transfer to the West Coast school because it is about 10 minutes away from home and I will be able to live at home with my parents which will be a huge support to me and my health and make it easier for me to perform my duties. In addition my doctors actually suspect that the "harsher" weather may be worsening my condition (and anecdotally I always do seem better when on the West Coast). I have no qualms about getting the required recommendations.
Complicating matters: The West Coast school was my first choice all along, but I was rejected. I accepted a position at the East Coast school hoping my health problems (started in undergrad) would be resolved, but they have not gone away. I do not want to disclose these health problems for fear that they may hurt my application. However, I don't have a really good reason to transfer without that, unless I make up something about departmental fit which is really not true since my current department is honestly a pretty good fit too.
