So i tested my sugar Level yesterday?

I'm always tired and getting headache but i've been like this for as long as i can remember. When i was younger my mom would take me to get checked ( sugar, iron levels) and everything was fine. Even when i was preg (twice) everything was ok. well lately i found myself not having an appetite, well i would get hungry but every time i would eat some it just wouldn't taste right. So yesterday i was at my moms and she tested my sugar level and it was 67. i tested before i had eaten. so now my mom is freaking out and thinks i need to go to do immediately. i think if i start eating right ( which i don't now) and cont. to check myself i should be ok right? Or should i just go? is 67 really low?
