Applying for a new job isn't easy even if you've not had a gap - I was in my last job for 13 years and the only reason I moved was because the site was closing and I was faced with either a long commute (almost 4 hours in the car a day) or redundancy. If you weren't nervouse you wouldn't be normal. Any help you need with translating your skills to wording for your cv or application just let us know.
