Good luck with your Social Security hearing. One of the things the judge will probably be interested in is exactly what your symptoms are, and how those symptoms prevent you from working *any* full time job.
Social Security doesn't just consider the occupation that you are inclined or trained to do. You should talk to your attorney right now, before the hearing. Tell them you are nervous and ask for their advice.
Do not feel like you need to "play act" or "act sick" with them. You know what I mean, the voice some people put on when they are calling in to work sick, but they aren't really sick, they are just pretending to be sick so they think they have to sound like they are on their death bed? You know how phony that is, and so do the disability judges. They know you can be very ill but still talk in a normal voice, be kind and pleasant and respectful, and sit in a chair just like you normally would. For example, don't limp if you don't normally have a limp, and don't use a cane if you don't normally use a cane, etc. They have all of your medical records and they surely won't be fooled by anything even remotely along those lines.
By the same token, you don't need to go out of your way to "act healthy". And I am sure you know what I mean by that. Like when you are going to a party, and nobody there knows that you are sick, and all you want to do in the whole world is just blend in and hopefully even make a new friend. So you put on heaps of makeup, have your hair specially done, send your clothes to the dry cleaners so they can be ironed for a change, and wear heels that absolutely kill your back, but you are going to sit in a chair anyway so you only have to worry about your entrance and exit. Then you take all your pills and try to remember to smile, smile, smile and act like you don't have a care in the world.
That is just as phony as the call-in sick routine. It is fine for strangers and can help expand your social circle when you are ill, but that is probably *not* the phony baloney that your attorney will want you to trot out for view by the judge.
The judge is going to want facts. Your medical record should help an awful lot there. If you really and truly are really and truly sick, you shouldn't have any problem answering any question thrown your way. Tell the truth -- without spit-shining it for the most "positive" spin and without exaggerating your ills to the point of absurdity, either -- because you will be swearing to it.
And plan something to help you de-stress afterwards. A meal out, a bubblebath, whatever suits your fancy. We'll be thinking of you, and sending good wishes your way.
