I dont get it

I know it's hard when you're trying and nothing seems to be working. But I'm so happy for everybody getting their BFP. I'm trying hard with no results and still I could never see myself telling somebody else to be "sensitive" towards me. It's a blessing ! Its so beautiful and they are truly lucky. So why do they have to be careful about what they say or celebrate a little less because I'm having difficulty? I mean its hard. But I would never let somebody elses happiness bring me down. Why not indulge in the positivity? You would want everybody to celebrate with you. So why not celebrate with them?
