Explaining on a CV that I left University without a qualification

[ChocolatChip]

A lot of you may have seen my recent little 'crisis' on Body and Soul the other day. And during this time I have done a lot of thinking and communicating with my family, trying to understand exactly why I feel the way I do.
And my unhappiness began 2 years ago when I began studying at university. Although I have just completed 2nd year, I am not failing and this year will have either got a high percentage 2:2 or just scraped at 2:1. But at this moment in time, I do not wish to go back and I am really struggling emotionally on how I will cope on returning.
I have struggled with a lot of the work, and have found that university is simply not for me. Despite being top of my class at college. I used to be able to find the positive side, and I was so happy to be going to the university of my choice and a degree that I thought I was crazy about. But I quickly realised by Christmas of the first year that I was not enjoying it and was really beginning to despite every part of university life.
I thought that maybe it was just a phase (sp?) and that it would get better. I even gave up a job I loved to concentrate on my studies. But here I am, almost a year and a half later, feeling exactly the same.
I have not made my decision 100% yet. However I have 5 months before I return. I have decided to test the job market and have seen several jobs I would like to apply for. However some of the things I have learnt on my degree will come of use in these positions.
How do I explain to them on my CV that I passed 1st and 2nd year, that university is not suitable for me and show that I have good experience that will be of use to them. Without them thinking I am a complete failure.
Thanks!

Thanks all.
I do have my ups and downs bednobs, yes. I have been like this for almost 10 years now, with no treatment, medicine or psychotherapy ever seeming to improve, no matter how hard I work at it.
Although I've always managed to find a way through or get to a point of coping. But I've been on a downer for such a long time this time.
Although your comment did make me smile a little
'sometimes life in general is a bit too hard', what on earth should I do to change that? Aside from maybe the permanent solution?

sorry, i dont have the answer and if i did i reckon i'd be rich! perhaps the sol,ution is to accept it and realise its you, not the course?
