Advice again

I'm still searching for info on this migration as its causing my anxiety to go through the roof. I have emailed CAB but the lady who called wasnt much help, she had to keep asking her supervisor. I asked if someone could go through the online forms with me over the phone, as I was unsure of some questions/answers as below. Not sure if anyone can help

1 Can we both use same email address as my husband doesnt have one & cant use a computor anyway

2 Will we lose the joint SDP & Joint Carers Premium we recieve in our ESA. As the only carers question I can see on dummy form is do u recieve carers allowance/care for someone 35 hrs pw

3 Will I lose my support group status money component & the additional money my husband gets for his age 71. Even though he gets state pension its deducted from my ESA

4 Deadline for Migration is 21st June could it be sent in 19th june so as I get my final Esa & rent

5 how do I get my council tax paid on uc? As with ESA I get both HB/CT paid except this year we have to pay £100.88 towards CT & dont know why

6 I will have to do my husbands migration form as not only cant he use a PC he'll be having cancer treatment & side affects etc I just dont want to stress him. Will all the questions be the same on his online form?

7 Where do you upload proof & what do I need? I have passports, CT letter, debit/credit cards, electric bill, water bill. I couldnt see on the dummy form where to upload?

I'm so stressed about this & worried about my husbands cancer diagnosis, I should be concentrating on that his treatments etc instead these migration letters have literally taken over my mind as I think I wont cope completeting them. My mind goes blank. So scared I'll do it wrong, hence trying to find someone who could go through it over phone when I do it.

Thanks for any answers & sorry for long post, but minds on overdrive
