I'm not being funny, but going on the sick will not do you any favours, are you getting help for your depression? I find too many people just go 'on the sick' because they can, what exactly is it that makes you think you cant work? Part of breaking the cycle of depression is facing the things that seem hardest, ive had a pretty shit 18 months and I only missed a month of work, some days i didnt think i could cope or even get out of bed, but my job gave me reason to, it gave me motivation because at the end of the day I had to feed my family and pay my bills.
If i had just been on benefits for one, i wouldnt have the quality of life i do now and 2. i wouldnt have had much motivation and dont think i would be where i am now.
With regards to the actual benefits if you did choose to go down that road, I think you would fall under income support/incapacity benefit which is around £60-£80 a week, depending upon circumstances, there is Disability living allowance, which is not means tested, but I dont think you would qualify as depression is not a disability.
You would also qualify for help with housing benefit and council tax benefit, though unlikely to be the full amount.
If you chose to get job seekers allowance, i believe it is around £40 per week, but you have to be actively seeking work to recieve this.
The emergency budget that came out on tuesday does not really affect the benefits for those on low incomes, the main change to the benefits system are that those applying for income support/incapacity benefit will have to undergo a medical assessment.
Those are the things I can think of off the top of my head, I used to work for the DWP , but have not done so for a while so things may have changed since.
Life is not measured by the number of breaths we take, but by the moments that take our breath away.
