feeling hopeless, just want to sit here and cry, my not-so-very birth story

Ok so we went into the hospital last night @ about 2:30am with contractions VERY close together about 2-3 minutes, I was doing GREAT! Contractions had started at about 5pm. We had lost the mucus plug that morning, had blood show, etc They took us in for testing to find (after 2 uncomfortable checks-one due to the nurses fingers not being "long enough") that I was 3cm and 80% effaced. I knew from the MW appt. that day that I was 2 cm and 80% effaced....so they suggested that we walk....so we walked for about an hour and they were about 2-3 min apart still, feeling stronger, but it wasn't as comfortable as home.
We chose to go in due to wanting to make sure the baby was ok (which she was doing great!) and thought that contractions that were 2min apart and VERY uncomfortably painful was a good sign. Well the nurse talked to the on-call doctor (because our MW is on call tonight from 5pm-sunday at 5pm) and he said that we could either stay or go home whichever would be more comfortable. We chose to go home--minimal interventions and we could progress better there, just to come back when were are "further along" So, very disappointed and uncomfortable we got all of our stuff, got into the car, I started to cry, and we went home. 5:45 am
When we got home we were so exhausted from not sleeping all night and I from the contractions, that we tried our bet to get some sleep. What a HORRIBLE sleep that was! I would wake up with a contraction, but was so tired and out of it that I didn't know what was going on and tried to struggle through each one, trying to remember to relax, but much to late in the contraction to be beneficial. My body calmed down enough for me to get sleep in between, but short, uncomfortable spurts...I got up this am feeling RAW and sore, contracting less often, about every 4 minutes, then fell back asleep between, woke up again to about 6-7 minutes apart, then am now "up" and they are spaced pretty far apart (about 10 minutes). I CANNOT do this again! 3 bouts of false labor, a failed early labor where I was contracting at about 2-3 minutes (sometimes even i.5 minutes!), getting checked, hooked up to the machine, pooing 50 zilllion times, and pacing the hospital hallways thinking THIS COULD FINALLY BE IT----to now feeling tired, raw, and back to square one....
ALL I CAN DO IS CRY! I can't do it again...I can't start over! The only thing i can think to do is walk...the thought exhausts me, everyone is bugging me and driving me crazy, and I am so very cranky, tired, and emotional! Is there such thing as temporary pre-pardom depression?
