Pregnant with #2 and feeling so impatient, am I the only one?

Hi, I am 20 weeks (half way, woo hoo!) pregnant with my second child, our first is a boy who is just 2 yrs old and the sweetest little guy...we planned this pregnancy (unlike the first) so I have known the first day of my missed period that I was pregnant, and it feels like just getting to 20 wks has taken FOREVER...I guess I am just feeling like 20 more weeks is so long away...I have a bunch of friends who are pregnant, or just had their babies, and my due date is the very last out of everyones, they will all have their babies before me, and I know it sounds stupid, but I feel jealous when they have their babies...I just feel so impatient and everyday feels like it's going by SO slowly...I am so thankful to be pregnant, and I keep telling myself everyday to just sit back, relax and enjoy the process, but it's getting harder the more of my friends give birth and I am still pregnant...anyways, I know this sounds silly...I just wanted to make sure I wasn't the only one feeling this way...I know 40 wks will come faster then I think, and I just need to be patient.
