I hear you. I've been waking up with this empty feeling daily. Some days I can keep myself busy enough to sort of ignore it, but as soon as I leave my internship and am driving home it creeps in again. I start to get anxious about being home, and don't know what to do with my time. Usually I just eat and watch TV to drown out the bad feelings... But then I hate myself for overeating or being lazy. Sleep and TV have pretty much become my hobbies because they allow me to just to feel like a zombie and not think.
I realize I get really irritable when I'm around other people. I hide it pretty well...But inside I'm really agitated. I think it's partly because I'm jealous...I don't know how they're able to feel happy or laugh about everyday things. I hate myself for this.
