How I Feel Living an RV Parked My Friend's Yard

I am a mooch, and I'm ashamed of myself. I don't want to go inside; I just want to stay out here in the RV. It's easier to stay in this little bubble, protected by the thin walls. I want to do this as long as I can. I don't want to look my friend in the eye because of the shame I feel. I know that I should go discuss life with her, and find out her expectations, but I don't want to do it. 

I'm tired of mooching, but I continue to do so. I should get a job, but I don't. I'd rather do nothing, than contribute to the matrix of lies that is the government. But I feel like I am taking advantage of a friend. 

I justify my continued mooching with weak rationalization like: 

"My friend works for the government, and gets paid way too much for the job she's doing. I'm just taking back what I put into her job in the first place." 

or

"My friend invited us; we didn't ask. If she doesn't want us to be here, she'd ask us to leave."

or

"It's not like we're costing her much, and we're even paying some of the electric bill."

Like I said, weak.

Should I make it a priority to leave, so that I can stop mooching? I would have to start paying taxes again. This is such bullshit. Government is the most fucking evil invention ever conceived, I swear.
