In reply to JackWelsh97:
Think about your positioning relative to the anchor and your climber - sitting facing slightly sideways (whilst still being seated directly in a line between your anchor and second, with the rope to the anchor taut, so any pull from the climber runs through the rope to your anchor, rather than just pulling on you) might help a bit with getting into a less awkward position for taking in. You can test it by building your anchor, putting the rope through your belay device and then (before you belay) tug down on the rope running out of your belay device down to your second. And then take in a bit. Do you have everything oriented in the most comfortable way, including for locking off if they fall? With the wrong set up you can sometimes end up a bit twisted.
I assume you're also extending your gear when you're leading to avoid drag-? It's perfectly possible to create drag if you don't do so and you're not using halfs (not sure why someone said you wouldn't at Stanage - there are some meandering routes and creating drag is a common mistake for new leaders who are just focused on getting gear in anywhere).
Belaying at the top is quite awkward to get used to when you first start, especially left handed if you're right-handed, but this doesn't seem to get talked about that much in courses. When I very first started I used to go out with my mates to somewhere accessible like Burbage and just practise building anchors and belaying without leading first. If you're doing things right (assuming you've been taught properly) it will get easier with practice.
And yes, if you look up anchor building on YouTube you'll come up with a lot of guide mode and bolted belay set-ups from North America. They don't rig anchors like we do - single pitch trad routes often don't involve topping out. Reputable UK guides or the BMC are the resources you need (and the V Diff website or the 'red book' climbing guide are decent too).
If you're not confident though (and I think we're all struggling a bit to understand exactly what issue you're describing), go out for a day with someone who is *definitely* competent, like an instructor.
