Penelope,
How's it going? Did you apply for Voc Rehab through the VA?
Did you apply for TDIU? Since you are at 60% for CFS alone you do meet the scheduler requirements for TDIU. Also, your income is below the poverty level (as you get SSDI) so you meet the income requirements for TDIU.
The Unemployability form 21-8940 asks to list your last 5 years of employment -including time lost from illness which would support your claim for IU. You can attach information to the 21-8940 form to explain more such as accommodations. Along with the TDIU form, I included a resignation letter that I had from my last full time position stating I resigned due to my medical condition. I was granted 60% for CFS and TDIU with the help of a veteran's lawyer.
