anemic

hi so about a week or so ago i passed out early in the morning and went to urgent care,the doctors said it was probably dihydration and that it was common in teens,even though i drank water and had an icepop right before bed.They didnt run any blood tests or even a finger prick but did do an ekg.Since then ive been feeling very lethargic and get very weak sick and tired feeling even if i have already eaten and slept.My skin is a blue green pale white which even though i have always been pretty pale people are commenting on way more now.I do often get anemic on my period (it was confirmed by my doctor)and it runs in my fanily,but when we were at the urgent care the physician said the sign of anemia is paleness inside the lower eyelids but i dont have that although i have looked up symptoms and have all but 3 out of 20.Im assuming i should get blood testing done but id rather try stuff before hand because i tend to pass out when the needle leaves my skin.Im on my period now and cannot stand without feeling like im about to pass out.Im also vegan but meat was never a large part of my diet,it was only something i had very rarely since my mom was a vegetarian until recently.Any recomendations or common experiences please share im feeling quite freaked out and afraid right now
