Sleepy in Response to Anxiety: What Can I Do?

Yes, after all my energy is used up in fighting the anxiety and I start to feel calm again, I get major headaches and really sleepy. Sometimes an overwhelming sense of euphoria followed by fatigue. You're not alone in this.

I was also wondering if my anxiety medication plays a part in my exhaustion as well. I've been taking them for around 2 months now.

Definitely. My body is getting tired from being in stress for too long. Sweating, fast heartbeat and breathing - all these symptoms weaken the body and make you more sleepy and exhausted
