I have severe waiting anxiety

Yeah I really do..today my car was in the shop getting the brakes done and I needed someone to pick me up from home to bring me the mechanic to pick up my car.

I luckily got a ride and they said they would be here at 11am..great I thought because at that same time my job called and asked me to come in early. I really wanted to because it would be considered overtime for me and LOVE me some overtime (time and a half baby!) So I told her my situation with the car and told her I should be there soon.

So 11am rolls around and no ride, my anxiety actually started around 10:50am because I had an odd feeling that my ride would not show up on time. At 11:15am I get a text from my ride stating he will be here in 45min because something came up..I was upset, but I can not control this and I did need a ride. So 12pm roll around (45min later) and still no ride! NOW I am MAD because my job called me and said that they no longer needed me because someone else was willing to come in..URGH..I just lost potential overtime over this! boy was I upset and nervous about when my ride was coming..what do I do while I wait for someone for a time that I have no idea when they are realing coming. I didn't really want to start something and then not finish it or have to leave it in 5 min or 1 min..the anxiety kills me! He finally shows up at 12:17pm and I got my car..FINALLY! BUT my overtime is gone and I was really sad about that..that is why I HATE HATE HATE relying on other people..you are on their time and I don't like being on anyone else's time other than mine. I honestly had no other option. I am going to try my darnest to avoid situations like this in the future.

AND yes I get this frustated when doctors appointments are late or any appointment for that matter. I show up early because I value and respect your time and my time, but then that courtesy is never returned. If a doctor is running last, at least tell me so I can decide if I want to reschedule or wait it out...JEEZE!
