Anxiety or depression

What does anxiety or depression feel like? I'm a sahm & I'm not sure how I feel right now. I don't feel happy. I don't feel.. I guess anything? Idk this feeling. Not sure how to describe it.. I can't even focus on one thought, its like I have so many going through my mind that I can't just think & focus on just one. Idk what's wrong with me, I'm not shaking or anything. I'm just sitting on my couch, baby asleep & feel nothing.
