Guess I'll be that guy and say I'm just not enjoying this at all.
I get that this is some sort of attempt to have this big reveal story-arc and I'm just supposed to have the patience wait through this kind of nothingness thats going on until you get there.
I don't want to. What you've published so far isn't that interesting or entertaining.
Please don't take this as though I'm just pissing all over what you're trying to do, I want you to succeed and I think the idea you presented originally has some merit.
Let me point you towards at least flipping through or picking up , at your books supplier, one of E.C Segars Books (the guy who invented Popeye)

I think this is very inline with the angle of this and the regular strip you were doing.
Depression and agoraphobia are incredibly heartwrenching but at the same time there are ways to make the topic and entertaining, on that I think "Marbles: Mania, Depression, Michelangelo, and Me: A Graphic Memoir" by Ellen Forney
http://www.amazon.com/Marbles-Depression-Michelangelo-Graphic-Memoir/dp/1592407323
is a another good resource.
Anyway good luck with the strip.
