TTC along with brother in law...

I'm kind of really upset! I announced to my best friend who's dating my brother in law we are trying to conceive and she tells me her and her boyfriend are trying too.. Liked and my boyfriend have been wanting a baby for 2 months and her and my brother in law just started being together not to mention she just lost a baby tht wasn't his. Like I just I don't know what to do I'm trying to be supportive but I just feel like whenever I'm ready to start a new chapter, someone else takes it..
