How to better myself and keep busy or gain work?

I am a mum of three children aged between 6 - 10, I have been with my man for 11 years & in that time I've never worked as after school we became pregnant with our first child & I've been a stay at home mum ever since. We got married three mths ago which kept me very busy with planning & organising of the wedding. But now I'm stuck on where and what to do from now., I have tried applying for jobs but no luck as I'm little qualified and no experience.
I feel so alone all the time not to mention bored as the kids are school aged & my hubby works full time. Little hobbies like scrap booking doesn't excite me to much as I've done it all before and it's nothing new or exciting to do everyday/ I really want to work and get a job just so hard when this town isn't the best for gaining employment. What am I meant to do? I'm afraid that I will get depressed soon if I just stay at home all day long with no company as it's happened before I would cry all day with it all building up. it sux that all my family and friends work every day I feel hopeless and like a idiot cos I'm always doing the same old shit
Has anyone else been in this position? What did u do about it?
