H3rmit, from reading your thread you are seriously way more AMAZING than you know!!!
I completely get/feel how dark, empty, meaningless, pointless, never ending, overwhelming......... (?) things must really feel for you
And you're coming out with "Sure, I'll finish my class and probably my degree, just a couple more credits. I committed to it, so I'll do it"!!!!
And I know it's not a matter of "enjoyment"/real purpose for you but...........!!!
So behind there H3rmit, I know it might not feel like it but, you've got some serious strength/resolve/determination. And that is awesome!!!
OK there's the depression holding you well back/down, there's a channel (significant to you) for all of that to find, but help/support with the depression, finding a way ahead you want to go down IS possible!!!
And I'm not going to tell you just focus on working towards (or wait for!!) a "nice" house, a "nice" job, a "nice" family...........you go for whatever is going to do it for you, you have so much about you, and there are so many options out there when you "think outside the box", when you think outside of where you are now/all you can see now.
But first, before anything/else, some help with the depression, hey?
The most important thing!! You've obviously really tried, maybe got "help" before now, but you need more, right? So doctors? A therapist? Talking about things? A support group- even if that's on-line (even if that's us, we're quite good, you know!! )?
Just something more.
And perhaps use them/that to best suit you e.g. write down/use bits from here........from there..........anything that might make even a little difference.
I know there are no quick, easy answers, and it can be a real hard journey to something better.............but you H3rmit.............well I'd say you've definitely got it in you!!!
