Hi, I'm not sure if I'm in the right spot. Admins please move me away if I'm not. 
So I'm a really new cyclist. The last time I cycled was probably 7 and probably only once. I was having financial issues and so bought a old bicycle for 35 and changed the tubing due to flats. (and apparently it's a mountain bike; will that affect my commuting?) Long story short, the bike is now fixed and I desperately need to use it.
Which I did, but only 1 mile away from where I live (every fortnight). I'm quite okay except at traffic lights, I feel so scared of staying on the bike and crossing it once the lights turn green. I'm really scared I can't 'start' the bike well. (but so far still okay)
Now I have to travel 6 miles, 4 days a week to school. Which makes it 12 miles a day.
I know this might be a stupid question but do you think I can make it?!
I obviously do not want to start a journey on a bike and then having to walk the bike for an hour to my destination. (not to mention I would need to cycle back)
I've searched google upside down and it seems that 6 miles is a pretty common distance every new cyclist does. I just have no idea if I can do it.
And also a few questions; On some roads, there aren't any cyclist lane and it's only one lane for cars. What should I do? I feel like I'm blocking the road for cars and it's apparently illegal to cycle on the pavement. What I usually do is to get off my bicycle and just push it until I see a cyclist lane or a double car lane. I don't think that's how people do it... except me. Any advise?
