Hi lostmywind, OK first the "laundry list" cover some of the things up on that/put them out of your mind, hey? It's completely understandable how you might be feeling overwhelmed looking at x amount of things.......and wondering how on earth are you going to make it through a fraction of that, and feeling any energy you have zapped away by just looking at......thinking about.........One thing at a time, hey? Just pick the things to start with that matter most and work your way from there. And you can only do what you can do, right?
And with your girlfriend have you really told her exactly how you're feeling. I'd hope she'd understand if you did, but if you haven't who knows maybe she's thinking you're not as interested in her or the relationship anymore.
Likely it's hard to keep that interest with the way you're feeling, but that's a bit different than she may be thinking.
I have got to say, really good on you for trying to push through this and gather the willpower to try to break through, though. And real kudos to you for that!!
But it sounds like it isn't at all easy, and sometimes at times like this it just takes a little extra help. And there's nothing at all wrong with that. In fact it's really good that you're sharing it with us!!
And I'd second the- get a checkup with your doctor and take it from there. Whether it's physical or whether it's depression at least you're going to have somewhere clearer to work from.
And you know while you're going to/getting it checked out we're still around if you want to talk.........if we can be there for you/help/support you in anyway.
Oh, and btw welcome to PC!!!
