Struggling

I’m really having a hard time at the moment my husband and I have been TTC for 13months now, last year my sister in law gave birth to a beautiful baby boy who was unfortunately too beautiful for earth, since then we have decided to put TTC on hold because honestly we couldn’t imagine the pain it would put his sister through if we told her we were pregnant, however the need for a baby hasn’t left my mind for a single second I can’t stop thinking about it my body craves it I feel like a selfish person for feeling like this knowing what his sister must be feeling it’s even close to what I feel, also my brother and girlfriend have just announced they are pregnant after only trying for one month and I can’t seem to get my emotions together I’m jealous, heartbroken for my sister in law, happy for my brother and scared for the baby hoping it makes it full term healthy I don’t really know what I expect to hear from this post but I just need to get it out there
