It feels like I'm so mentally exhausted all day everyday. This suddenly happened overnight and hasn't left me for 3 months. I wake up and have such extreme mental fatigue and it's debilitating. The only thing I can think of that happened is, that same night I had a huge anxiety attack for the first time ever and it happened multiple times a few days after too and now I just have generalized anxiety all the time. I am sleeping but just not well. Could this be the reason for feeling so sleep deprived and if so how do I fix It to get good quality sleep again and fix my mental fatigue?
