Do you ever feel

Today has been such an emotional rollercoaster. Actually, scratch that. This whole week has been an emotional rollercoaster. Lately I feel like I forget to breathe sometimes. I feel as though my world is getting smaller and smaller. Kind of like in movies where the character is in a room then suddenly the walls start to move closer and closer together.. something like that. But anyway, do you ever feel like maybe it's all mental? It's all in my head, this anxiety I get. I've been able to control it at times, but with all the chaos lately it's getting so much harder. My anxiety has gotten so bad, that I've had to call out of work. I need to stop letting this control my life.
