Shari, I don't think you'll have a problem keeping your benefits either if you take one class at a time online. Just, realize that it will mean you have to go through the longer form CDR which you must treat seriously--almost as if you're starting a new application. You will open a can of worms by attending school--I do believe it'll be a small can of worms though.

Would a slight delay until after your CDR has been successfully processed make your life a little easier? If it's a short wait, I'd consider it...

And I might sound like a hypocrite for suggesting this to you...but your situations are very different.

Having your doc/s be supportive is helpful. It's impossible to be approved without their help, but their support isn't enough to ensure approval either.
