Remind me why I am even trying

I think I lost my pencil case at university. It's not in my bag, not anywhere around here. So I guess I forgot to pack it yesterday and it's now lying somehwere in a lecture room. Or someone took it already, which wouldn't surprise me, so there actually is no sense in me hoping that I might get it back next week.
I am feeling kind of detached because of it. I mean I am sad about losing my favourite ink pen and the necklace which was in there as well but I am not really thinking about it. Those things are replaceable. What really bothers me is that my Paddington Bear pen from London was in there, too and I could actually write with it (without crippling me fingers). So now I am without any useable pen and I think I need a new pencil case as well (meh my poor tiger one). I really thought I packed it and I can't remember seeing anything being left on the table but then again I am bad at remembering things.

So this doesn't actually do much to improve my mood. I am generally feeling blah but I am kind of uninterested as well. If that even makes sense....
