Just... given what you've shared previously, C, you're really
not within the confines of a semi-normal family. Your parents have been, at the last, outright abusive -- if you were living in a better area, they would have almost certainly been in jail a
long time ago -- and there's nothing even remotely normal about that. They are, in fact, terrible people, and you've not been in an even remotely normal situation.
That doesn't mean they don't have their good moments or whathaveyou, no, but the net is... almost certainly negative. Understand where you're coming from, though. For the longest time, I tended to describe my father as "a good person, when he's sober". It took a while and a good deal of (badly needed) separation before it really internalized that he was still an abusive fucking alcoholic, the good points didn't even remotely make up for the bad, and that no amount of rationalization would change the fact that he was not someone I (or anyone else, really) needed to be around. The latter in particular was always something that proximity really seemed to encourage -- there's definitely a degree of urge to look positively on people you're forced to be around regularly, even if that urge is frankly self-destructive (in the sense that it reduces the motivation to get the hell
away).
... also, your earlier post, the energy and whatnot. Pretty much textbook clinical depression
Not sure you can really do anything about it in your situation, though, besides soldier through until you can get away from your incredibly toxic living situation, start making a decent one for yourself, and hopefully either see it pass by naturally as the environmental stressors change in nature/go away or at least be able to safely seek proper aid for it.
... in any case, best of luck and all that. Know it only helps so much when you've basically just got that urge to pass out and sleep half the time, but hopefully the well wishes'll help at least some.
