Hi i a female-18 years old and recently i have been having symptoms such as ecessive thirst and feeling dehydrated ( i drink over a gallon of watera day and am still always thirsty) also i have been feeling exhausted alot but at the same time very anxious/distacted. Also i get dizzy often (usually when i stand up) and i also sometimes get this like nervous twitch etc. At first i attributed these symptoms to the antidepressants that i take ( i used to take zoloft and abilify now only zoloft) but lately they have been getting worse. Someone suggested to me that it coul be signs of diabetes however, i find that hard to believe bc i have gotten routine blood work not to long ago and everything seemed normal... Should i be concerned and get tests done or do you think that it may be something else...?
