Have I suffered from anxiety? Hell yeah, I suffer from damn near everything. Too much football, wrestling, SCUBA , skydiving and car crashes in a former life. I even rode a bull and a saddle bronc in a rodeo once (VERY short rides). Take it from someone who can barely reach his shoestrings to tie them sometimes. If there's no physical pain involved, move on to the next problem. Short fingernails are no problem...all 9 of mine are short.
Seriously though, anxiety is a bitch. I used to dismiss it as so much bullshit from some wimptoids. However, after having gone a round or two with it later in life, I can see that it can be a real problem. Thank goodness that my episondes, maybe all of three of them, have only lasted about a day each. But that was enough for me. If it's an everyday kind of thing, I'd say definitely get a little professional help.
