Have you asked VocRec for an in-home assessment (independent living services)? This WILL help your claim for IU! This will show what your daily routine is currently, what time you get up, who cooks, cleans, does the yard work, etc. etc!
I had an ILS counselor come to my house, was the best thing that I could have done. Once the counselor was in my home, we had a discussion about my current unemployment and future employment. Once he told me that I was unemployable thru our conversation for my SC'd conditions, I then asked if he could put that down in a letter for me. HE DID, and once the rater seen that letter from him. BAM!!! I was awarded IU immediately!!
Good Luck!
