For some time now I have been wondering if I'm under long period stress without really knowing it. My heart always beats fast (100-115), unless I sleep (75-85), and stress could be causing it. I don't have many symptoms, but sometimes I can feel some kind of tenseness in brain and body, like I'm going to explote or get a panic attack from high anxiety level.

Is it possible that I'm stressed, even if I sleep well and don't seem to get effectef by it most of the time? Or is it an anxiety problem, that I don't know the cause of?

I just really want to know what is going on, because long period stress is really bad and I have had it for at least a half a year now, this tense feeling that sometimes pop up.

If needed, ask me to get more information.
