Just to reply, I am on higher care DLA and ESA support group. If you want to receive an anything don't tell them you're capable of using a computer. In their eyes, you're perfectly fine if you have concentration good enough to drive, study or write something logical out. If you can drive, then you have good manual dexterity, so you're capable of work.
If you want to get anywhere, you need to tell them you can't use a computer or phone properly, you can't communicate with people (computers and phones included) and struggle to get on. If you fail to show them this in a medical, they will leave you with nothing. You can have as much medical back up as you like, but if you don't put on an act they will think you're lying. Their job is to filter the claimants out, not to hand out benefits freely.
Be very careful and read up on the atos examination. It's not fair but that's the way it is.
