Hello missouchalot
As you've gone through the ESA application form, you've presumably answered all the questions and explained how your various illnesses stop you from being able to perform certain tasks, so I think that all of your illnesses will be taken into consideration.
If you've also included a list of your medications, then that will back up what you have said, and I assume you'll have made a note of the fact that you're awaiting referrals?
It would be a very good idea if your Mum could write down how she has to help you, and explain how your illness affects you, from her point of view. It might also be an idea if you include a diary of how your condition affects you from day to day (not a great long diary, just a few days' worth!!)
Other than that, I'm afraid you'll just have to wait and see what happens. Good luck with the application.
