Is it normal to feel like this?

Do something for yourself. Like to better yourself or to make just yourself happy! That should help! Whether it's going to get a massage or taking a yoga class it may help.

dont try too hard to make yourself happy. I tried that too much when I was in highschool and working. I spent all my paychecks on crap I dont use.

Just wait it out. you'll feel better after a while

dont use all your energy in making yourself go from "hungry" to "full"

People have a lot of suggestions, but it might be hormonal or chemical.

Be outside more, run, play, get some natural endorphins pumping through your brain, drink lots of water...

this is not something I've experienced personally, but I think a lot of ppl do. I heard ppl talking about it on the radio the other day. They mentioned this huge, hungry hole right inside your body that nothing could ever fill. Some ppl use drugs, some religion, but the hole remains. I think they concluded that the only thing that really helps is feeling connected to others; even in the smallest interaction you have with them; simple things like smiling more, sharing a joke and even small helpful gestures towards others :)

yeah its normal, we all have weird feelings sometimes. go hang with your friends or just something fun that you enjoy. maybe something big happening will make you feel better.
