That sounds a bit toss. I hope you do start to feel better. 
No worries about any links or anything. 
There is a lot of new stuff to play with, but you honestly don’t need most of it. As long as you can type and press reply you’re pretty much sorted (and they’ve invented paragraphs now too ).
If you do see something on your travels that you like the look of and fancy having a go at then you can ask questions and have a play around in the Sandbox (and I jotted some stuff down in a Forum Quick Start Guide too, if that’s any help?).
And the (eg) @Ian_Chimp Mention trick is good for getting people’s attention.
