On the Mend with a Side of Feathers Rustled

Slowly I'm getting better. My voice still sounds like a 14 year old boy going through puberty, but hey, at least I have a voice. Earlier this week all I could muster was a raspy whisper. ***** Now, onto my rustled feathers. I've had K's 18 month DR appt scheduled (& turned into Killjoy) for 2.5 months. Killjoy tells me Receptionist has jury duty that starts on 2 weeks, the same day as K's appt. She "puts me on notice" and mentions that I will probably have to reschedule the appt. Keep in mind, I turned in the appt time 2.5 MONTHS AGO! Anyway, I try to be proactive and get it changed and the damn b*tch Killjoy tells me that the day I chose won't work because Receptionist has to go to jury duty "pre" meeting. WTF?! I shouldn't have to reschedule shit. I gave more than enough fucking notice to begin with. I get another appt (& thankfully the DR office Receptionist was a sweetheart about my calling 3 times) and it was ok with Killjoy. The point is, I'm pissed off with myself. I should've just kept the first appt. I should've just told them tough I can't get another appt scheduled so they're just have to deal. I fucking cave in, trying to be proactive, and it gets me nowhere. What do I get for switching around things? Nothing. No "thank you", no kudos, no recognition of any kind. That's why I'm upset - I change my life around and expect something/hope for something and I always get nothing AND I know that's how it ends every time and yet I keep falling into the same damn "trap". I seriously need to pull my head out of my ass...the sooner the better.
