Thinking of throwing in the towel....

Me and my husband have been TTC our 1st child since July of 2016, and nothing. So today I found out that his mom's Boyfriends daughter is pregnant with her 1st(and she doesn't even want kids), and it felt like I had just been smacked in the face. so all I wanted to do was go cry in a corner at this point but I couldn't because we were in public. So we get home I cry (am still crying) and I look at my husband and say "I just don't know if I can do this anymore..". I am so tired of crying Every time Af comes and Every time I get a BFN and when I see my friends getting pregnant. I just don't know if I can do it anymore. I want a baby so bad but when it doesn't happen I get so sad to the point I don't even want to get out of bed. Sorry for the long post I needed to vent and I really can't talk to anyone about any of this....
