excitement vs anxiety

I've figured out lately that it's sort of hard for me to distinguish between excitement and anxiety a lot of the time. My boyfriend is on the other side of the country for school and he's coming home for a visit in a week. I've been thinking about this and I know I am excited about it but often the elevated heart rate and emotional energy make me feel like I'm starting to panic. No wonder I don't enjoy doing things and having fun! Every time I feel happy I start to panic... This sort of goes hand-in-hand with my fear of working out lately. My body identifies any stimulation as the onset of panic...

Oi vey... I really need to work on this.
