Um. Well, I might've had some of those symptoms when I had anxiety. I guess what you are really looking for are some answers...
Yes, most of those symptoms could potentially be anxiety - but my guess is that since you are suspecting yourself that your symptoms are anxiety induced, and the fact that you posted in the anxiety and stress forum - very well tells me that you know you are stressed out and anxiety and are suffering from those symptoms. What I tell people to do most of the times is to just try to calm down and relax as much as possible. Of course it would be even more beneficial to sit down and figure out who or what is causing your anxiety in the first place, and then figure out ways of dealing with those problems...
If you have any more, specific questions - post them here.
