I am stressed about work - I have been totally committed to a project where I literally gave up my life to work on - having no social life, working weekends, and putting in over 200 hours of overtime in a matter of 1.5 months to get the job done - then because of a technical (IT) error - and stress - something went very wrong and now I'm feeling guilty, I've let everyone down, I've let myself down and now am having problems feeling confident about work - I panic when my phone rings, I can't eat or sleep, I have been dealing with all the negative feedback from this and feel I'm all alone - even if my managers tell me it wasn't my fault and have been supportive I can't let go of this feeling and it's giving me panic attacks and making me sick to my stomach - am I being too hard on myself? I've gone from being a 100% supporter of my organization to wanting to quit and move to another country.... whats wrong with me? Is this a mid-life crisis? How can I find ways to relax and let go?
