I'm at work and i couldn't sleep at night because of my anxiety, now i'm here and i feel really tired and it's giving me anxiety, should i take mypill?

Maybe: It is very important to have a diagnosis. Sleep disorders can come from many different problems. What appears to be anxiety may be something else. Consult your primary care physician or a mental health professional to determine an appropriate course of action.

Call your doctor: If you have been prescribed medication by a licensed physician, you may want to contact him and ask him if this is inappropriate situation for you to take your medication. Anxiety medications tend to cause/increase fatigue and tiredness, so it may not be the best time to take it, but that is between you and your doctor.
