Personally speaking if someone has such a great difficulty training at a level expected for beginners then they should not be there. I don't think Aikido should be the first line of therapy for damaged psyche - the same for any martial art.

In Shodokan Aikido we don't toss beginners into full blown randori - we basically start at simple avoidance exercises. If you can't do that then please leave and come back when you can. I have, Honbu has, been quite patient with a few who have problems but the operative word is try.

In Judo (at least here) you do randori from day 1. Too much for you - you should go elsewhere. Like Aikido there is only so much adjustment the group is required to do.
