Last night when I was falling asleep, I could feel myself hyperventilating and getting more anxious. And I woke up to my partner playing the cookie clicker game on his phone (it's not new to me, and I'm usually perfectly fine with it). But I could feel my brain and heart racing faster as I hear the clicking sound. 

Eventually I told my partner to kindly turn the volume down and I tried to calm myself down. Took a few minutes of silently crying to bring myself back to sleep.

Is this an anxiety attack? 

ps. Haven't been feeling well these days and I finally decided to go for my first therapy session during the weekend. Do I need to bring this up to my therapist?
