It was suggested to me for years to apply for disability. After a longstanding, successful career I was really hesitant the income from it would not suffice. I did apply and was accepted and happy I have time to heal, get the help I need with the insurance provided and it dated back to the date I became disabled (started therapy with a PTSD diagnosis). The only guidance I got from my doctor was to let it all out. Go to the appointment(s) as if it were the worst of the worst day. Dress as you would if having a bad day at home. Discuss the worst things that actually go through your mind. Having a professional background I was very hesitant to take the suggestion. As it turned out, I was so freaked out by the medical review that social security asked me to do that I was actually in a pretty bad state of disassociation when they interviewed me. Even though you are using an attorney, it is likely you will (if in the US) need to still have the medical/psych exam at a location determined close to you by the state you live in. For me, the location was in a pretty gnarly part of town, which amplified my PTSD even more. The symptoms were in full flair mode and I did not try to restrain one bit. It is the truth I was living with at that point in time. Though the process is daunting, for me, it has been worth it. Processing and therapy and other health issues can be time consuming and costly. Had it not been for giving myself this time to get on board with getting better, I am not sure where I would be today. The provided insurance has been so beneficial. Hang in there and let it all hang out at every meeting you go to. This is a huge step for you and don't take for granted how hard it can be for us with PTSD.
