Are the sorts of jobs you are applying for what you really want to do? I have remotivated myself at times by taking a course (in same/different subject) or reading self-help books, etc. Think of ways you could use your time on things you wish you had had time for before, when you were working, but didn't? Do you write or do artwork, volunteer, etc. You have time now and getting "out" and about might help you meet a contact that can lead to a job. Being around other people can be very energizing and motivating. Do you belong to any business "breakfast" clubs or anything? Professional organizations?
