I went semi-vegetarian (actually, pescetarian*) during this summer break. At first, I tried to balance appropriately the proteins and nutrients, but then, I experienced a situation of total stress due to a change of school during my senior of high school and let's say that I forgot about nutrients.
Different teachers, tons of homework, lack of sleep (I slept like 5-2 hrs per night), new classmates and bla, bla, bla. During that month, I had my menstruation normally, but I was tired all the time. Then, after (more than) a month passed, I noticed the lack of menstruation.
One week ago, during my midterms (where I started to sleep like 4-2 hrs after sleeping at least 5-6 hours finally after the first month of school) I noticed increased hunger, anxiety, and more fatigue. Now, I'm finally resting more, and I quit "semi-vegetarianism", but I'm still feeling so, so hungry (especially I crave carbs), and I still lack menstruation. I don't feel as tired as before, but I notice that I feel sleepy in the afternoons. What should I do?
Note:
-I only ate fish like twice per week. (*) Other times, I ate proteins, like eggs, soy, but I think I didn't have enough.
-I took some vitamins.
-I guess that due of the lack of sleep, during my midterms I noticed really bad memory, but I mention it just in case.
-I'm 17
