Fun in the ER...*sigh

So today was the day of my second interview for a position as a Vet assistant. But after only spending about 45 minutes, while standing I completely blacked out. I fell backwards onto the floor and then came too. I have no idea how long I was out. No one seemed to give 2 flying fucks about me and I basically felt pushed out. After I walked myself home I blacked out again in my apartment. I called my doctor and they said go to the ER so that's what I did. The first ER gave me a exam and then said we cannot help you- go to this one at #$#$@%E%^ so then I go there and they were like "who are you and why did you get sent here? You should go here ^%&%" So then I go there and I'm finally helped. I swear I did every test under the sun and they even made me drink juice. After everything they concluded that it was something to do with vet clinics and stress. So that leads me back to square one, I'm going to pull myself from running for this job. And as crappy as I feel, I just don't want to black out again. My mom says I got to role with the punches. I told her that's all that's been happening to me. I keep getting punched!
