Don't know if I feel like throwing up or I'm just hungry?

DaFiveEight

I'm at 2335 cal so far and I just woke up from my nap. I kinda feel sick and when I drink water I felt like I didn't want to drink it at all. So I'm just going to wait to get naturally hungry, anyone else feel the same? I'm striving to consume 3000 cal by the end of the day, really gotta gain weight (only 130 lbs want to get to 145-150 lbs).
