Thank you, everyone. She's proud of me, too. She made a Mass Effect in-joke while telling me so, which sorta reminded me of the fact that our interests are so similar (I got her into Star Trek, in related news...) that it's currently hard to hold onto a happy thought, because all my interests became our interests.
I've read about people saying that after separating, so I know it's not a me thing. It happens with a lot of people, and I just happen to be one of them now. It will definitely take some time before I can really enjoy many of the things I enjoyed, though. Oh well.
Some of the advice I came back to here tonight is really relevant to this particular moment, in fact, as I just woke up a short while ago from terrible nightmares involving her. In the first one, she tried telling me she wanted me back, but somehow all I had to respond with was a keyboard which notified me of who was trying to contact me and their initial intent (or something). I scrambled to type back, but I couldn't know whether or not she received it, or how she felt. I guess this nightmare is rather self-explanatory; actually, they've all been, lately. Very blatant.
The point is, I guess I need all the reminders I can get right now that I need to carry on for me, not specifically for future attempts at a relationship with her.
