Baby name disappointment...feeling guilty..

Can anyone throw some tips my way to not feel so upset that my best friends sister is choosing the same exact name? I feel so damn guilty for feeling the way I do. I know she’s excited for her child like I am mine but it just is hard. I know forsure pregnancy hormones are making it worse for me. I had gotten pregnant I had been TTC for quite some time and we were so ready and a month after I had named mine, her sister came out that she’s pregnant and naming hers the same thing stating she has had it picked since high school. I’ve tried being excited for her but I still find myself feeling upset and feeling upset turns into feeling guilty. So please if anyone has any tips to just shrug it off my shoulders do share!
