First solo 5K

Never thought I would ever say that! 
So I signed up to do a 5K, a local one, at night.  Mom was going to do it with me, but I kept changing my mind and plans got all screwy...
The day of the race I still wasn't sure if I was going to do it.  I had already registered, but honestly was scared to do it alone.  I didn't have anyone pushing me, like the last one, what if I get hurt, what if I can't finish. 
There I go again being all supportive and confident in myself.
Even driving over to the course I wasn't sure if I was going to make it past packet pickup.  It was a smaller race - only about 100 people doing the 5k but there was also a 1/2 marathon, so maybe 300 people.
I walked up to the table, got my shirt and my bib and turned up the music.  I thought if I just act like I'm supposed to be there, no one will notice that I'm terrified.
Half Marathon starts.
5K starts about 20mins after.  I'm at the back of the pack....for the entire run.  Of course everyone starts off jogging.  So I do too.  Bad decision.
So now that stupid voice in my head starts in about how the course goes right by my car....
But I don't, I didn't. 
I basically started arguing with myself.  I know that sounds crazy...but at that point, I think I'm the last one, I can't see the ones in front of me and people are starting to pass me coming back....I was trying to tell myself that what I was doing was great!  No matter depressing and embarrassing it felt.  I couldn't compare myself to others -
"No!, you will feel worse if you quit, no matter how you do, you are doing it!"
That was pretty much the conversation I had with myself the entire 3 miles.  I kinda became my own motivation -  I had to prove myself wrong!
I would jogg some and walk alot.  I was really nervous about running in the dark and the roads weren't smooth - no inclines but the road was "bumpy" for a lack of a better word. I'm gonna say that slowed me down too.
Anyway - so I get to the end - jogg to and through the finish line....a camera flash goes off.  I'm done!!
I did it!  The clock showed 55mins.  The picture shows my eyes closed, exhaustion and that I have a long way to go!
My next race is July 17th.
