You could advise that you are taking a break fromyour studies - you don;t need to go into the details on your CV.
If you are callled for an interview, then a prosepctive employer is interested enough in you to meet you for a face-to-face conversation, that's the time to discuss your uni situation.
It's always possible to put a positive slant on these things - remember, they will only ever know what you choose to tell them, which gives you a large measure of control, something which you probably feel is absent from your life at tht moment.
Education is never wasted, so if you do decide to leave university, take away the knowledge and experience you have gained and turn them to your future life, and put aside the bad feelings.
The hard part is acknowledging that university is simply not for you - copntraryu to the government's current obsession, not everyone wants to go, or is indeed suited to university life, and there is absolutely nothing wrong with discovering that, and acting on it.
The sad thing would be if you remained for the wrong reasons - to please others or to avoid being seen as a 'failure'. It is your life, you control it, and the opinions of anyone else are just that - opinions.
You know what you are, and what you are not - so be positive, and move forward with your life in a way that makes you happy.
Remember, no-one will be waiting at the end of the line with a gold medal because you 'stuck it out' - life is about choices, good and bad.
Rejoice in the next stage of your life - everything is waiting out there for you to go and take hold of it.
Good luck!
