Time to quit.

So, I am really feeling like it's time to quit trying. We have been trying for over 2 years. I know others have tried longer but I just feel like it's hopeless now. Literally every other couple I know has or is having a kid? How am I suppose to cope with that? We can't go to a Dr. to get checked because we can't afford it. I've never even had a chemical pregnancy. My uterus is so empty it echos... so over all of this. It's not fair.
