Frustrated!!!

I am so totally with you!! I was married in 2002 and got pregnant 3 months later, we had a beautiful baby boy! I then stopped taking the pill in July of 2005 to have another. We have been TTC since then and to no avail!!! I have gone through every possible emotion. I am SO frustrated b/c it seems as though everyone else can get pregnant...even the people who don't want it or in my opinion deserve to be pregnant! Meaning people who don't take care and stop their bad habits of smoking and drinking and dangerous lifestyles!!! I don't do that and CANNOT get pregnant!! I so long for my child to have a sibling!!! He loves babies and would be a GREAT big brother! I know, I am absolutely happy that I have one child, but my husband and I come from big families and long to give that to our son, but it doesn't seem to be happening!! Our families keep asking when we will have another...I have prayed and CRIED so many times...I am angry and sad, I have so many emotions going through me. It really hit me hard when my brother-in-law told my husband that they may be pregnant and they just started trying in January 2007!!!!!! It is SO not fair!! I don't understand!?! Why is it SO hard...I had one, why can't I have more!? This is the first I have spoken(written) about it, I have not told anyone but my husband my problems. I just needed to vent and when I saw that you all were feeling the same way I just had to let it out!
