I have copd, (getting worse), and back and neck problems. I am still working, but it's getting harder every day. Am I eligible for SSI? Thank you.

Based on your work record, you may be eligible for Supplemental Security Disability Income ("SSDI" or "taking your retirement early") and, if it is not at least $783/month, enough SSI to bring it up to that level. Eligibility for either turns on a functional analysis:  on your ability to do a job, not just your current job. You can apply online at www.ssa.gov.  If you are initially denied, you can request an informal conference.  You only need a lawyer if you are denied and denied and denied and must appeal to an Administrative Law Judge.  You can find one through the National Organization of Social Security Claimants' Representatives.
