Baby?!?!

Many of you already know why I am depressed most of the time, so don't feel obligated to read this... I just need to get some things off my chest.

As many of you know, Matt and I have been trying to have a baby now for almost 2 1/2 years...and I am starting to wonder and worry if we will ever have kids, I mean...Matt and I have both been promised kids, but when??? I know that things don't happen on my time...and that sucks...I hate it, but I need to know that there is hope for me. We have both been to the doctor and neither of us have anything known that could prevent us from having kids. I am just so upset. Wouldn't it be awesome if you could just pray for something...and you could get a specific answer, such as...not right now, but in approximately 2 months...wouldn't that be nice?? I think so.
Matt and I are not at the age where it has to happen now or it is never going to happen, but for us...we just keep wondering how much longer we are supposed to wait. It is KILLING us. Matt handles it better than I do, but it just seems like everything I ever thing about is having a baby. I know that if we come to a point that we can't physically have children that there are other options, but is it so wrong to want to have my own children? To be able to experience that? To know that the child that I am getting is a little piece of me and Matt?
I want a baby so bad...and then there are people out there that could care less if they have kids, or treat their kids like crap. I was adopted and my parents never hid that from me, so because of me being adopted I have always wanted to adopt a child and give it a second chance like I was given, but I want to do it AFTER I have my own children. It makes me so angry when I see pregnant people that are complaining about being pregnant. A friend of mine told me of a story that when her mother was in relief society a woman stood up and was complaining about various things that were wrong with her children, they were sick. Apparently, another woman behind the one that was complaining stood up and was unable to have children and said "what I wouldn't give to have a screaming child."
I always wanted to have kids young, and now that I am a little older I am REALLY grateful that I didn't because of things that I may not have gotten to do if I did have small children at home, I got to go to college which many women who have kids don't get to do, and many other things.

I know you are probably thinking that I am only 22 and have my whole life ahead of me, but having my own family is my life...I feel so empty, almost like I am missing something. You're right I am only 22, but alot of people don't have to try for 2 1/2 years, and every month cry and feel worthless. I just don't know if I should be worried or what??? Are Matt and I doing something wrong? Or are we doing something right and this is our test and trial in life?? I just have so many questions...I want to know why it isn't happening for us, and if it does happen WHEN?? I feel so alone...and although I know there are people out there that know exactly how I feel, I feel like nobody knows how I feel and what I am going through.
