So I Was Diagnosed As Anemic Around The Summer Of

So I was diagnosed as anemic around the summer of 2015 because I was throwing up a lot and found that I was deficient in iron. months passed and I've been feeling better and stoped throwing up. My diet has been excellent, breakfast lunch and dinner. Fruits, vegetables and water. But as of this week I've been continusly feeling this undeniable pain and urge to throw up. I'm not sure what's causing this again. I'm more than sure it's not psychological.
