Blessed and a little (bitching and moaning)

Well here I am at 34 weeks and I can not even believe we have come this far. I am so incredibly blessed, and I know it. I have the most amazing husband, even if he does piss me off on purpose sometimes, I know that me and my kids are his number one concern. He is so good to me and would do anything for me. I love him so much and he trully is my rock! I also have an incredible son, who makes me laugh every single day and gives me every ounce of love he has in his huge heart. He is so perfect for our family and I dont know what I would do without him. For over five years we hoped and prayed and prayed and hoped for one more child to make our family complete. Eight months ago God blessed me once again with a miracle. I trully believe this baby is a miracle, just as any other baby is, but I think my baby is just that much more special. (dont all moms?) I know that this baby boy is special and he will complete us as a family.
Now dont get me wrong, it's not all rainbows and butterflies over here. I am so done with being pregnant. I know most(or all) pregnant women feel that way at the end. I am in so much pain, it seriously hurts to walk. I dont sleep and when I do it is not good sleep. I am exhausted and all I want to do is eat. I have gained less than 10 lbs,  but I feel like I have gained at least 80. My spine feels like jello. My back is killing me. My house is such a wreck and I dont want to clean it. The contractions are really getting the best of me. It is hard to do so many everyday tasks. Grayson kicks so hard sometimes I literally double over in pain. I am so grumpy I feel bad for my family. And a little depression has definitely set in. I told Jared just tonight, I dont want to go anywhere or do anything. It hurts so bad just to walk. We went grocery shopping tonight and by the time we were donee I was so spent I had to lay down for a little bit when we got home to recoup. It is just the last day or two that I have been in this much pain and this exhausted.
 Is this normal???
 I was not like this when pregnant with Grant.
