It's really hard to think of something that doesn't also carry with it anxiety or sadness. One thing that comes to mind is singing along with my favorite songs - if that's not happy, at least it's relaxing and liberating. Although for some reason I've been doing less of that recently, and feeling little urge to.

I also really enjoy it when my cat cuddles up to me in the morning. But most of the time she's an indeciferable whiny *****, excuse my French.

Also I don't know if it fits "happy" but I always look forward to stretching while watching Netflix before bed. Although I'm trying to move this to after I wake up because I feel that it's not doing my sleep much good and I want more to look forward to getting up.

I don't know, it's all kind of unconvincing. (Not to mention, not job material.) Anything productive comes with anxiety, feeling inadequate, sadness or even anger. And I'm not even sure if there's a grain of happiness there at all, or it's just obsessiveness and hopeless, fading ambition.
