It is so draining!
I start yawning, so I go to bed at night. As soon as the lights go out, PING! LOOK! There are all of these things that you need to think about, worry about, and I can go on and on and on for hours. In the meantime, I'm pleading with my head to shut up and go to sleep, as I need to be up soon. I wake up every other hour as it is, and then fret about sleeping through my alarms.
Work? Oh, look at all of these things that could possibly go wrong today! You can know everything about how to deal with the problems, but as soon as it happens, everything useful goes out of your head and you start to panic, because it's going to make you late, and your manager will have a go at you.
Driving in an unfamiliar area? Look at all of the things you could possibly crash into/kill! And oh, look, someone's coming the other way on a road that's only wide enough for one car at a time. Panic while you reverse. Driving lessons and tests were horrendous, because I struggle with being observed.
I fret about seeing people that I vaguely know, and don't feel entirely comfortable with, in case I say the wrong thing. I panic about being late. I do not cope well with changes; I like routine and planning. I have to stop my hands from flexing so that I look normal in front of people that I know. People are the worst thing for my anxiety, but unless I move to an uninhabited Scottish island or something, I'm going to have to persevere and put up with them on a regular basis! I can't go to so many places because they are too busy for my head to cope with.
The sweating, sudden stomach cramps and rushing to the loo, panic attacks, crying episodes (I'm recently back on medication, which doesn't help), tight chest in situations that make me anxious, etc. do not help. I'm generally fine by myself at home (thank goodness I'm off with stress at the moment), but when I'm out and about, forget it.
I'm desperately trying to do new things to make me feel braver, but it's hard to get past the anxiety to get out and go to do these things.
