There's no shame in being disabled and unable to work. Apply for SSD. But, get a lawyer. You have a better chance in SSD's eyes if you have a reputable disability lawyer. Expect to be rejected on the initial application. Don't be surprised if your appeal is denied. The third and last stage is a SSD hearing. Lawyers don't get money from you. The government pays the lawyers when you are awarded your disability. And, the government pays you retroactive to your initial filing date. You get it in one lump sum. 1/3 of this sum automatically goes to your lawyer. Most who apply for SSD go to a hearing. The reason is a certain % of those who apply initially, don't file an appeal, a certain % whose appeals are denied don't follow through to the hearing. It's a system SSD uses to reduce the number of people receiving benefits. I was told this by a person on the inside of the workings of SSD. Another reason for a lawyer, is SSD, for those with back injuries and knee injuries, are perceived to be scamming the government. Finally, keep a pain journal every minute of every day. Where your pain is, how severe your pain is, when you take your pain meds including the dosage, the time, and their effectiveness in relieving/reducing your pain... or not. Note in your journal how pain meds affect you ie. how they limit your activities. And, how your pain limits your activities. Note your depression and anything and everything concerning the disruption of your life minute by minute. Keep this log current and detailed until the end of the hearing. Make copies of all of your applications and your journal. Don't just hand them over w/o keeping copies for yourself. I hope this helps.
Let me know how it goes for you.
