control what you can control
..... I'm having more trouble than usual because of the builders banging about all day. Thay have their lorry engines running as they deliver and thats a major trigger for me. I've been trying to escape to the gym but as I'm already edgy this is proving to be an overload....
I found you have better control of your environment if you invest in industrial safety hearing protection (I use headphone style ear muffs, ~30 DB noise suppression). When used in combination with walkman earbuds and with your favourite music or just the TV, well, even really bothersome outside noises are tolerable enough. [My concrete apt. building was doing a lot of jackhammering for months, it was either that approach or just be anywhere else -- back then I merely had anxiety issues, but such intrusive noises were still too much to tolerate.]
While you certainly don't want to hide from gyms and outside noises and such, still I figure you need to have some control over just when and how much of an annoyance like noise you have to put up with.

Great approach! You get a very similar benefit during treadmill workouts by merely extending the duration at a lower intensity, compared to a shorter but more vigourous workout at very high intensity. Are you tracking your "aerobic zone" (target heart rate)? Just scale that down a notch or two and up the duration.
And, perhaps a big bonus: the longer workout session works in another way as it helps acclimate you (get you used to) the social setting of a bunch of people working out by letting you hang around longer, and all that that may eventually lead to. Better yet, if you're not really 'pushing it', you're less 'isolated' from the others, and have some extra attention and concentration available to focus on your surroundings when you care to.

ps. (further to Lisa's suggestion) I've not reached the point of confronting my issues while dampening my reaction with CBT, but it sounds like something worth trying, figuring that practicing at building a tolerance for a trigger in a controlled setting can sometimes be a workable way of learning to better handle it.
