I had a miscarriage 2 years ago… & it’s been the hardest thing I ever had to deal with…

I’m still TRYING to get over it now…I’ve been doing well for a while until my foster sister had a baby… Every single time I see that little girl, I get so upset. But at the same time, I’m always holding her and changing her… I even felt a little weird for wishing she was mine. This is bringing up old pain…

Idk what to do.
