I think, there is too much energy accumulated in you due to various reasons, making it difficult for your body to relax. I'll suggest take deep breaths, (exhale time should be greater than inhale). Just try to relax body with each exhale. If possible, read first two chapters from the book `Attention revolution - by B. Alan Wallace`, and practice it for few days. If nothing works, seek professional help either from doctor or meditation teachers.
