in a rut.... youngest starts school, cant get a job and getting clucky..

Hi ladies, I don't know if I am asking for advice or simply just having a rant. long story cut short, my youngest is off to school next year, I've been a stay at home mum for the last year which I have loved and now having no success getting a job for next year, which isn't good because I need it to pay for my study through the day..I had a pregnancy scare a few weeks ago which has made me question if I am ready to not have anymore kids, I was scared at the start but started to get excited about the possible idea... basically just confused, has anyone else been in this rut before, advice, stories would help...just need some positive motivating help to know I am not alone, Thanks
