Hi James, I hope you’re keeping well 
Those horrible chancers are just trying their luck again - they do it loads in the hope that those of us that can no longer be on our A game will just give up and go away. Definitely go for the tier 1 tribunal mate. It’s not easy but, it is worth doing. Put the kettle on and grab a pad, a pen and their last letter (this is the bit that will take most time)
Number out their sections that you disagree with (I disagreed with every single zero on mine)and, put down your frank, honest answers of how they got it wrong and, what your difficulty is and how it effects you daily (don’t be proud -give them everything. I have rolled forward off the toilet halfway through using it before because of a focal aware seizure. Now my missus won’t let me shut the door and, the dog sits there looking at me wondering what’s going on
)
This will be your notes for filling out info on line for the tribunal service. (Do get help for that bit if you need it it can be less taxing that way and, a second pair of eyes for these things is never a bad idea) Once they’ve got it they will start work behind the scenes for you. DWP often will try to put things right in the case quickly because everything in the tribunal is charged to them (the people involved, the room needed, your costs for getting there, the lot and, there’s a chance that a tribunal may award a bit more for your trouble (that has happened before)
You possibly won’t have to attend a physical tribunal either (I didn’t)
For the work thing - again don’t be proud - now is not the time for that. Understand your limits and pace yourself within them. I took a 40hr a week job last year and, all I got for my efforts was a Tonic clonic seizure and 2 days out for the count in hospital.
As @Hank_Dogs says, your condition isn’t going to get any better now(Sorry mate)
You can also claim Universal credit to help keep your head above water. I do. It’s not a wage and, I’ve had to tighten my belt quite a bit but, it makes sure that I can pay the important bills.
There are a few places that can help with making sure that you’re claiming what you’re entitled to. Even help with all the forms. I think one of them is CAB. someone may mention some of the others soon.
Do please go for it mate - your life doesn’t need to be any harder than it is now.
Take care and, all the best 
Jon.
A strange fact to end that my Mum told me - pack animals like dogs, will often maintain eye contact when they’re pooing because they’re vulnerable at that time It’s a pack protection instinct. Still a little odd though
