Feeling extremely hungry and unsatisfied lately. Why?

Soo about 2 months ago I went from eating 1200 calories daily to 1360, losing half a pound a week because I'm only a pound or 2 away from my goal. I started working out every single day for at least 30 minutes a day in January. I think I may have missed maybe 3 days of no exercise in the past 2 months. Sometimes I do 45 minutes or more but it's always low impact cardio, walking/treadmill, or dancing. Yesterday, in all I did a combination of different low impact cardio routines for about 2 hours. I didn't even burn off all the calories I had went over that day (I still needed to burn off about 300).

The reason I even had to attempt to burn off those calories yesterday is because lately I've been getting so hungry and always go over my calories. I have no idea why. Now it's so easy for me to go over by 500. I don't work it all off though, so at the end of the day it all just adds up, I guess. Like today, I had a Special K flatbread for breakfast, a few cookies, and soup for lunch. Then by 4 I was literally starving, I had 380 calories left but felt as if I hadn't eaten all day. I had just had the soup around 2pm. THEN my fam bought Captain Ds later and I went crazy on fish, hush puppies, fries, and shrimp. I would say I ate well over 1000 calories in that one meal. Now I don't even feel full. I actually feel as if I could eat more. No indication at all that I ate over 2000 calories today. I haven't even worked out.

I don't understand why all of a sudden I feel like whatever I eat is never enough. I'm never full for longer than 15 minutes top. I know everyone will say it has something to do with how often I work out, but like I said, although I do workout daily, I never do anything too extreme that burns many calories. If I was working out that "hard", I'd be losing weight. I've actually been stuck at the same weight for about a month now. If I am losing I'm doing it very slowly, so I doubt my exercising has anything to do with my constant hunger/appetite. My activity level is still set at sedentary too. I'm afraid to set it to lightly active. I'm a college student and I do walk back and forth to class and try my best to avoid sitting for long wherever I am, but I work from home and am generally lazy. This all happened all of a sudden. I have no idea what is going on with me or how to fix it. And yes, I get enough protein and drink enough water. So bizarre.
