This is a kind of long question but here i go. I've been having terrible headaches and i've been extremely tired , but have trouble going to sleep at night and i seem to be really thirsty and i have like snot coming out of the vaginal area. And if you could help me i would really appreciate it. Thanks.

those are really vague symptoms...I'll try to address it one by one.

First of all, how old are you, are you on any meds, are you physically fit overall (no hypertension, heart conditions, diabetic, etc, etc, etc)

the headaches...how bad are they? is it pounding, grinding, sharp, throbbing, any specific part of the head?

tiredness...are you eating enough, sleeping enough, do you exercise, etc.

sleeping at night...how many hours do you sleep a night? do you take naps during the day? anything to stress over?

thirsty...do you drink plenty of water during the day? do you eat extremely salty/spicy foods?

"snot coming out of vagina"...what color is it? does it smell bad? Is it possible you have an std?

the thirstiness could be related to the vaginal discharge...as you could be dehydrated. The thirstiness could be because you're not drinking enough water...or you could be diabetic. The tiredness...could be a million + 1 things...not sleeping...etc. Could also be diabetic.

Do you urinate often?

sorry, I know it's not very helpful, but those symptoms are so very generic...that only a visit to a doctor could potentially help out.
