Sorry to hear how difficult things are for you.
Most people who go to tribunal with help win. Please contact your local Citizens Advice Bureau and ask them to help. They might have a waiting list, so the sooner you get in touch with them the better. If they say they can't help, ask them who else in your area does welfare rights support and ask them to help you contact them.
Lots of councils have something called a 'One Stop' shop. Its a place where there are council staff to help with all these kind of problems. They can fill out forms for you, you just tell them your answers and they will write it all down for you.
There is alot of support online but its in writing and that doesn't sound like it'll help much! But, if you do want to join a group or forum for support they will all understand your issues with writing and reading.
Try to talk to your doctor, tell them what you have told me and how you feel. Pain can be treated. If you are having to lie on the floor because you're in too much pain to get up then you need more pain relief.
You can phone Social Services to get help for yourself. You don't have to wait for a Dr to ask them. The phone number will be on the website for your local council. Tell them what you told me; that you are not coping, and that you feel so desperate you want to die if you don't get help.
Ask social services for an Occupational Therapy assessment. They look at how you live and see if there is any equipment or techniques they can teach you which might help.
Don't be embarrassed to ask for this help if your home is a bit messy! They have seen it all and they'll understand.
You can phone people just to talk about how you feel. Mind Charity are good, and Samaritans always have someone there to listen. You don't have to give your real name if you don't want to. You don't even have to speak to the Samaritans when you call if you feel scared or embarrassed. Sometimes just being able to know someone else is there is comforting.
If you get stuck on the floor because of pain and can't get up yourself then the paramedics will come out. I usually think its best to stay on the floor for a little while and see if I can get up myself, but if you've been there more than half an hour, if you think you've broken a bone, or you're bleeding phone for help straight away!
Keep a mobile phone in your pocket all the time so you can phone for help if you need. Even if you haven't got any credit you can call 999.
Phone your local MP for an appointment. They call the times they meet with people surgeries. If you can't get out at all you can ask for a home visit or for a phone call from them.
Please don't feel embarrassed to leave a comment on my blog - everyone here is disabled and we all understand. No-one will judge you for your situation or spelling!
I have put this on my blog because I know you have subscribed and will see it. There are lots of people reading in the same situation so they might find it useful too.
Come back and look at the comments. There are lots of disabled people and lots of specialists who read here - they will have more ideas about how to help and will leave them for you in the comments thread.
