In all honesty, I think the best thing to do in your case would be to take a few days, maybe a week or two, off and just enjoy other activities. This'll help rid you of the 'why can't I, I have to..' mindset.
Also, when you do feel like writing out a tune again, DO NOT start with working on your EP. Just make a casual loop or something even more trivial, just for kicks. Most of the people I know who have experienced writer's block (including myself for huge amounts of time) was because they had developped plans and projects and started pressuring themselves - not to do something, but to do something GOOD - and it killed off a lot of creativity.
I'd say the watching tv / listening to other music is definitely a good way of taking it easy on yourself. :-)
Good luck finding that inspiration again mate, but above all, enjoy it!
