SN10,I must say it sucks to be you @_@'
Joke aside, it sucks to be alive, so you are in good company. Well, I guess you don't give a dam about that, do you? ^_^ Apart from all that negativity, I must congratulate you on the smiley she sent you, I can only speculate on the magnitude of the internal struggle that led to the emission of that single ideogram. This back patting being complete, I must warn you that you should not underestimate the fuckness of her circumstances. Having a nice face is no protection against life shittiness and internal mindfuck. If she complains, assume she has good reasons to. After all, if it was so easy, she would have solved her problems long ago, don't you think? Thing is, you both seem to be love idealists. That makes things even more complicated, but at least you should understand each other quite well...
As for the home front, it seems to me things are pretty simple,if not easy. Your father is in full dereliction mode, and on a mission to crash through the bottom of the pit he threw himself in. Likewise, your mother seems to be waiting for something to crack, and dutifully doing nothing until then. Because you seem to have decided to not leave the house (you should realize that this is a decision, and take responsibility for having taken it), I think it's way past time that you kill your father. Of course, I mean the metaphoric kind of killing. Take over the running of the house. Just check that your mother won't oppose you, and then relieve your father from household responsibilities. You don't have to be confrontational about it, it's enough to be assertive and act. He's way too weak to resist you in any practical way, although he'll give you hell just for sports. You live in that house, so you have the right to do what is needed to make it a livable place. I don't know how the money enters your household, but it would be good to secure the access to the lines of income, at least as much as possible (your mother's welfare, if not your father's). Your mother could be your ally. She seems to be a wimp, so you should get there with some diplomatic arm twisting. You should also establish some strict rules about where your father can hoard his junk, and parts of the house which are commons and hence forbidden for junkyard purposes.
As for your application documents, why don't you publish them so that we have a look at it? Obviously you should anonymize the parts that could lead to your identification, but without taking so much that it renders the exercise worthless. I can't promise anything will pan out of this, but at least you may hire one or two brains to provide you with useful input without disbursing much. Use something like google docs to convert your CV, resume, etc into an online format.
Finally, since I feel whimsical and you spend your daily 6 hours in front of the computer, why don't you waste some of that time reading about personality types as defined by the enneagram model?
http://www.internationalenneagram.org/system_and_types/index.html#subtypes
Read about the different personality types, and try to find where do you see yourself fitting the best. I'm pretty confident it will be the personality type 6, but see for yourself. If interested, you can see typical patterns of alienation or development for type 6 personalities:

It's not like this is going to save your butt, but you may feel somewhat relieved to see that your dysfunctional life and personality fit into well known patterns. This may in turn make you try to learn of adapted strategies to get out of your hole. At the worst, you will be somewhat entertained, it's quite fun stuff, like reading your horoscope for laughs ^_^
