how bad can iron deficiency after donating blood affect you?

hi.. 5 days ago i donated my blood for the first during a blood drive they conducted in our university.my hb level was normal. i didnt feel much tiredness right after then. but as the day came to an end, i began to feel unusually sleepy. i thought,"okay... may be its because i donated blood my body needs some rest." i had some juice and went to sleep. the next day was also fine, but my arms felt kind of painful. somewhat like nerve pulling. when i told this to my mom, she assured me that this could be expected since i lost blood. that night i slept at about 1am. note that im strictly an early riser. but that day i slept straight for 10 hrs. it was like i was out cold.my roommates tried waking waking me up several times but i never once heard them. when i woke up i tried to stand i felt like i was about to fall. i had some food and tried to get some of my works done. but i couldnt concentrate. i kept zoning out from time to time. i felt really fatigued. i took a leave for the day.

since then its been like this. i feel constantly tired. when i try to take a walk, i feel as if im walking like a zombie. since the day i gave my blood i have already lost around 3 pounds. my skin looks pale, i have shortness of breath all the time. my legs feel restless. like i said before i cant help sleeping straight 10 hrs for the past 3 days. if im sitting or lying down, i feel almost normal. but as soon as i try to do something, its back to feeling dizzy again. i cant even enjoy eating my favourite food. even that makes me feel dizzy.

i had been diagnosed with low bp a few months back. back then they said it was nutrient deficiency. and now 2 days after donating blood im also having my periods.

my friend says it might be symptoms of iron deficieny. thats when i stumbled upon this blog. should i be worried? or will it pass soon?

It's really impossible for anyone to diagnose you over the internet, and none of us on here are medical experts, just folks like you.  The first thing I think you need to do is see your doctor and get a blood work-up to see if any nutritional deficiencies or other things pop up.

thank you... and yes, i just got my blood checked. my hb level which was 13.5 was down to 10. and now im getting an earful from my folks for not looking after my health.
