Ok please excuse my rambling that's sure to follow but I would very much appreciate any advice and some listening to help me get my thoughts straight!
I've never been to university, I dream of having a history degree. I've always had an interest in the subject for as long as I can remember. I'm now 34 and my youngest starts nursery next week so I'll have 2 mornings and an afternoon to myself per week and dh says he'll take the kids (10, 8, 2) for as long as needed on a weekend for me to have peace and quiet to study. I've registered with the OU and I'm ready to select my first module so realistically I could start this in October. I'm just having trouble with believing in myself I guess 
I'm aware it's going to be tough but I want this so much. I'm just worrying now that maybe I'm not intelligent enough, or maybe I'm not as articulate as I thought! I'm telling myself that logically, as long as I just get my head down and get on with it, work hard etc I could do it right? Sometimes the thought of 6 years is a bit off-putting but those 6 years will pass regardless and maybe in 6 years time I could be just a little closer to having a job that I want to do, rather than looking at my prospects now which seem to be little considering I don't have a degree or many qualifications at all.
Now the morbid bit - dh was diagnosed with cancer last year. He was told in March that he's now in remission. I'm worried all the time now that it'll come back and kill him, and this worry makes me think maybe I shouldn't take this on just incase this does happen, I don't know how I'd cope. I realize this isn't a rational thought and I can't 'not' do anything ever, just incase it came back but I guess I'm not giving myself enough credit for my ability to cope with things. I know I can't just sit tight doing nothing, just incase the worst happens.
Lastly, anyone here studied History with the OU? I know it's not ideal for some but logistically I don't have the support/childcare to attend a brick uni. I'm aware I need to be very disciplined though!
Any advice/support/encouragement most appreciated!
