Struggling with PCOS

We have been TTC for almost 2 years now. I went to a new OBGYN and he was impressed with everything I've been doing! I started my first round of clomid last Monday! Yesterday we were at my parents house and my little sister (20 years old) called and announced she is pregnant and I litterally burst into tears!! And people just kept telling me to "relax" and "when you least expect it, it will happen." "You'll have your turn". Is it just me, or are those litterally the worst things to hear?!!
