I just filed my SSDI online 2 weeks ago and wanted to post on my experience in hopes that it helps others, especially the severely brainfogged like me. For me, the online process was horrible. I don't want to discourage anyone from doing it, but after what happened to me I feel I need to post this for those who may have substantial cognitive problems. Doing the online process made my brain much worse. I was in bed for a week with a night mask on to settle my brain and had to take xanax. I felt like I was having seizures. It scared the hell out of my husband. Its now been two weeks and my brain still isn't right. If I had it to do again, I would definitely go with an atty or a representative. I don't want to misrepresent this so please understand that the online process is not complicated. I only want to fairly warn those with severe cognitive problems like me who may be trying to decide whether to do it yourself or go with an atty/rep. Also, in fairness I need to state I was under a lot of stress with meeting a deadline. I had miscalculated the deadline by a month and had only a week to get it done. I worked on it several hours each day which is way too much for my brain problems. The online process is time consuming so it is important to pace yourself and take rest breaks, something I didn't feel I could do with my deadline. To clarify, I had a unique situation. I had initially contacted social security by phone in November where they started an initial application and sent me forms to complete. I went into flare lasting months and didn't follow through. Once social security starts the process you have 6 months to complete the follow through. So what happened is entirely my fault. I thought I had until the end of June, but miscalculated...I had only to the end of May. I called social security and asked what to do and they said go online and complete it before the end of May. Anyway, back to the online process, you can stop at any time and then go back later. Just make sure you write down/printout your return access password. The website does shut down, probably for maintenance, so those on the west coast with deadline filing especially need to be aware of that. For me, it substantially challenged my brain. Each response field allows a limited number of characters. It was very difficult for me and overworked my brain with all the re-writing to reduce answers to the space given. Thankfully I copied and pasted all my answers into separate MSWORD documents so I have my answers. When you complete the application it is supposed to allow you to print it out, but mine wouldn't print out. If I had not copy/pasted as I went I would have lost everything! I called social security and they said I *might* be able to get a copy from my local social security office. I haven't gone yet so I am not sure how they will respond to that request but will post on it when I go. I strongly recommend you copy/paste the questions and answers to a separate document so you know what you said as you will be questioned on your answers by different people throughout the process. I requested my medical records and sent letters to all the doctors I listed on the application giving them a heads up that I have filed so they don't get blindsided and will hopefully give responses that are consistent to what I said on my application. I'll put a separate post on the format I developed and hope it helps others. When my brain is better I will post more on the questions it asks. I have things saved into different documents, but my brain is still too shakey to handle toggling back and forth between lots of multiple documents.
