Does this ever happen to anybody else???

I guess it started out as irritability. I was irritated and didn't know why. I started snapping at my husband for no reason. He didn't do anything. My irritability was confusing. It always is. I started thinking about it tonight - trying to figure it out. I was focusing on the irritability and realized there was a sadness. I guess crying could help me ease the irritability. There is anger too. I guess irritability and anger (anxiety, I dunno) are one in the same. I have heard that anger can mask so many things. I get that and it makes sense. I am just having trouble figuring out what it really is...frustrating.
