Look OP - FWIW I understand how having a mental health condition can affect every aspect of your life. I have a personality disorder along with my physical conditions. So I understand why you might be afraid of working, and the realities of it.
But if you're a regular who has namechanged like you say you are, then you know what AIBU is like. You should also know that posts about benefits always tend to get a bit intense, regardless of the stance.
Your initial post did you absolutely no favours, and the way you have worded posts all the way up to you most recent ones have again, seen working as an "option", which is going to anger a lot of people. If you had stated you find working hard because of an anxiety issue right at the beginning, you would have got a lot more sympathy and practical help.
Find a new GP. Get a referral to the mental health team. Also try and organise some voluntary work - a few hours a week in a charity shop or something, to get you back into things, and help break down the mental barriers you have built up. Also might be worth looking into getting a book called "Mind Over Mood" which is a do-it-yourself CBT guide. You can pick it up for a fiver on amazon. It will help you work on changing those negative thought patterns and filters that you may be so used to having, you won't even recognise they are there, until you start looking for them.
Here is a page from a wonderful organisation called Rethink about working with a mental health condition. They have lots of free work sheets, and are fantastic for practical advice.
This is the link to the "Mind in your area" page, to locate your nearest Mind center. They are free, they tend to run a variety of groups, and have phone lines as well. I know my local Mind does a "How to get back into working" drop in, so maybe yours will do something similar.
You can't just stay like this forever. If for no other reason than it is so depressing in itself, you will be doing your mood and anxiety no favours. You need to fight against your demons.
Post again, phrase it differently, and maybe post in a different section, and you will get the support you need to help you change your life for the better.
Best of luck.
