Sometimes I have a whole day of anxiety. This is where I get what I guess could be called butterflies on my stomach the whole day. In addition my stomach/chest feels tight and I experince rapid heart rate as well as shortness of breath on and off. Yet, the butterflies and tight stomach/chest stays. Sometimes, it will carry over the next day. This can occur when I wake up on the morning but can often begin just before I sleep. I hope to wake up feeling normal but that's often not the case. Sometimes it'll be gone by the following day whether jrs when I awake or later on.

When this happens it's very hard to handle. Breathing exercises, meditation or general distractions may bring temporary ease at the best. It seems the best I can do at the moment is sit and wait for it to end. It can get so bsd where I feel sick. 

I assume that it can be regarded as an attack once I get the shortness of breath and rapid heart rate: I don't tend to get any other symptoms when this happens (feeling of general anxiety all day),nor usually in a regular attack. Nonetheless, the two symptoms can get really bad and only seems to get worse.

I don't even recall having heavy stress. I recall having slight stress around work and sometimes around my future, for I've been at some time at a crossroad, stuck between two somwhat life-changing decisions. 

Any advice on how to handle this situation would be very much appreciated.
