hi mountainboo, sorry to hear of your predicament, it sounds like you will have to finance it yourself, however, with luck your earning potential will be more after your courses so your investment will have been worth it. is it worth doing some work until september to save up some money to help? (cant really understand why you have given up now if your course dosent start till sept?)
with means tested benefits there will always be people who fall just outside the cut off and for them it's frustrating, however, i would take exception to "haven't had anything from the government" - what about child allowance? smp? the birth of your baby and post/ante natal care? education for your child?
i can see it's frustrating for you, but it might be better to count your blessings - i have a degree but would swap it for the ability to have a family
