need to vent

I need to let some steam off.. my husband and I have been trying to conceive for nearly 3 years (I know, not as long as some) but I'm so sick of hearing everyone's announcements.. my sister in law who doesn't have a job husband got kicked out of the military they live with my MIL and decided to have a baby.. it's just frustrating.. my DH and I both have great jobs, money saved and we are ready and we just can't. The one thing i should be able to do is reproduce and I feel like such a failure to my husband.. I'm so frustrated..
