i agree with sannah, fear is indeed paralyzing.
kind of going through the same thing, but it's in phases for me. this is a good phase, the internet doesn't interest that much at this point. but the things that i do to replace the internet aren't any better, so we're kind of in the same boat.
but one question - about your online courses - is there any background research that you need to do on these courses that you could do through books, or by making notes on paper? also creating a nice studying "atmosphere" can help a lot, ergonomy and stuff. though i guess if everything is in place and you use the study atmosphere for spare time surfing too it won't really make a difference.
if you're using a laptop, maybe try to moving it to another place and telling yourself "this is where i'll do my studying" and vice versa when you use it for gaming/surfing etc. just a suggestion.
and i hear you on the not relating to people issue.
