Your work history since 2003 is your strongest asset. The 2011 application doesn't make it easy for people to explain their disabillity. Use a separate sheet to document your work history. If you got prescriptions from 1 -2 places ask them to print out a prescription history and include that as well. See a psychiatrist ASAP and explain your history and ask them to support you in a disability claim. Continue to see them until you are approved. There are a number of supplemental forms that you and your doctor can submit to document your inability to function and hold down a permanent full time job. The Adult Function Report is a supplemental form you can complete. It's involved but really worth the effort to write thorough answers. Your psychiatrist can complete two supplemental form called Paychiatric Review Technique and Mental Residual Functional Capacity Assessment. They can be found at http://www.ssdi-help.com/ssaforms/ssa-forms.htm. Review both of these to get an idea of waht the SSA is looking for. Best of luck.
