Against all odds?

Yesterday was yet another emotional tough day at the hospital for me. While it was supposed to be a happy Ultrasound Monday, it had a little bit of worriesome news. That got me upset for the rest of the day. Everything pretty much stayed the same: My cervix started thinning, baby heads is down... However, my tummy liquid went up very high. Which is something I didn't wanna hear. Apparently, if I have too much tummy liquid, it gives pressure to my uterus. Which is not a good thing. And this time, I was above their limit too. I was so scared. Then the doctor thought, one of the causes could be diabetes. Which is another thing I didn't want to hear. Gestational diabetes is one of the most coomon, yet scary illness in pregnancy. Sadly, it runs in my famuly history. So I have a higher chance (a 50% chance) of getting it. When I was 6 month pregnant or so, I took the test and see if  I have high sugar level, luckily, I was tested negative.  But that was a scary thing I had to face.  When they told me it's possible I could be a diabetuc (because I have so much tummy liquid), once again I was freaking out.  I was not happy to have to do that test again.  For the whole day yesterday, I was in tears.  I also discussed with the doctor about the long term plan.  In two days, they have to cut out some of my heavy durty medicine, because it could affect the baby.  So,  the doctor gave me the best and the wrost case scenario:  The best is, when they cut off my heavy medicine, my contractions stay the same as it is,  Then after next Monday's ultrasound, if things are looking the same, I get to bedrest at HOME.  However, they still think the baby could come out, based on all the symptoms I have been having. I hold onto Oren for almost a month (in two days, it will be 32 weeks, it is A MONTH mark).  I was sad to hear, this is the best we could have accomplished, the rest of it is all going depends on natural factors.  The whole day yesterday was a sad day.  Then this morning when I redid the sugar test and guess what?  I was once again tested NEGATIVE.  Take that, NEGATIVE.  I tired to remind myself I could beat the odds that I can just keep Oren in a little longer.  Oh this weekend is going to be a real test for us. 
But let me ask you guys, how can a person still stay positive and strong when you think you have overcome an obstacles, there more new ones come up?
