Jealousy after miscarriage

Olivia
My best friend from preschool and I got pregnant a few weeks apart. I've had two miscarriages in the past so I was actively TTC but she wasn't. I had another MC in December and before this last time I would leave my jealousy for strangers- pregnant or with a child in the grocery store, mall, whatever. But now my jealousy rages, I've never been a jealous person but every time I think about my best friend I get livid. Do you ever experience jealousy like this? How do you deal with it when you do? I just want to spend time with my best friend without being mad at her for being pregnant. Obviously I know it's not her fault.
