Was self employed, now out of work, options?

Hi all,

I am at an all time low so please be gentle with me :/ I was self employed in a sole trader partnership up until recently. Things have been really tough financially, both at work and home, friction with my partner coupled with what I think was a mini breakdown* I really could not go on the way things were.

* I have been to the doctors, am on antidepressants and been referred to speak to Lifeline, although I am not suicidal

So, I am on the unemployed scrapheap :( I must point out I am 30 soon and never claimed a penny from the Government and have been in employment since I was 16. I have run through what little savings I had, I cannot fall back on family, I have a wife (working) and a small child (10 months old). I've been told I won't be entitled to anything as I essentially walked out - is this true?

I have rent looming, along with child care costs and living etc. In the process of claiming child care tax credits.

Any advice would be most welcomed
