I'm 12 and i think i might have P.O.T.S.?

okay, so, in like january (2010) I was in morning choir for school and we were standing on our chairs and i ped out. I fell off the back of the chair and probably hit my head. I woke like 30 seconds later and i sat up. the nurse came and brought me to the health office. My mom was called and she was told i needed to go home and she should probably take me to the ER. My mom's a nurse, so when we got home she took my blood sugar ( i hadn't eaten breakfast that day) and it was really low...she had me eat some food and took me to the ER. the doctor said i probably had the flu ( i knew that wasn't it). so, two days later i didn't feel good at all...i had a really bad headache and i felt dizzy, and i had eaten and my stomach hurt so my dad took me to the ER (same hospital different doctor) again and they took a CAT scan....the doctor then told me that i probably was hypoglycemic...then like...idk..in February or something like that...my grandma came over to visit and we went to the fabric store to get some fabric to make a pattern for my cousin's wedding dress...because i'm about the same size as my cousin my mom and grandma were gonna use me as a dress form...so they were cutting and pinning fabric when i suddenly got really dizzy and they said i was really pale so they had me sit down (this was after lunch and i had eaten) on my bed and my gram got me juice when my ma got the blood sugar taker thingy and before i drank the juice it was low...and even after I drank a ton of juice my blood sugar was still low. Later that day after my gram had left my mom was talking to my dad and said "i think she might have pots" well, i hadn't thought about that...but it made sense..cause my mom has it. I looked up that night if pots is hereditary and it said that it can be. So, i was just wondering if i could have postural orthestatic tachycardia syndrome (sorry if i spelled that wrong)
