Let me preface this by saying I am prepared to accept this may be impossible but it never hurts to ask so...here it goes.
Recently I decided to transfer to another location of the company I work for because I was unhappy with my previous geographic location. This move took me across the United States. My company offers a relocation package where they cover the cost of the entire move as long as you promise to stay with the company for at least 12 months. I cannot leave voluntarily or be fired "for cause." I was already not in love with the job but I thought the quality of my life would greatly improve if I lived somewhere that I greatly preferred to be.
I love where I live now but I am having major problems at work. I am feeling totally incompetent/unqualified and I have lost all interest in continuing my career. I was getting by at my previous location where I was working on a low priority legacy project but here it is the complete opposite. The required skillset is simply higher than I what I posses.
When I brought this feeling of inadequacy up to my manager, he began giving me more "simple" tasks but even those I am struggling to finish at a decent pace. I even mentioned switching to a different technical position but realized it wouldn't make a difference because I still don't have any interest in this line of work.
All of this has resulted in a constant feeling of anxiety and impending doom. Every moment of every day I feel anxious because I know that I am barely scraping by. Even when I am off of work, the only thing I can think about is the next day at work which terrifies me. I do not want to live the next 7-8 months of my life like this but I signed a contract and having to pay for a cross country relocation will be a massive financial blow.
I understand that all of this is my doing and I am paying the price for the decisions I've made. That said, what are, if any exist, my options besides repayment?
Edit: It's probably too late to include this detail but I have no desire to continue working in this line of work, for any company. I have poor stress management abilities and the anxiety is debilitating both at and outside of work.
