Sorry you're having a craptastic day. I had a craptastic three weeks and also thought, "I am freakin' SOBER now, isn't some of this stuff going to start to be a little easier?" Made me feel like a complete self-centered brat and...surprise! I was indeed acting like a complete, self-centered brat. But hot damn it felt good...in a bad sort of way.
It happens. As peanut suggests, just roll with it. It does pass. In the meantime, try to do something you enjoy as much as it feels like the last thing you want to do at the moment. I have found distraction to be key during these nasty moods.
And it definitely takes awhile for us to learn to like ourselves again.
In the meantime, I happen to like you a lot. Love your posts and your fabulous wit.
You'll get through this, Nuu. In the meantime, sending you lots of hugs.
