My sister is angry with me. Has anyone else experienced a similar situation?

I've had five miscarriages, no living children. I've been trying to be a mother for seven and a half years.

My little sister just gave birth; she got pregnant on her first ovulation after she started trying to conceive, then had a perfect pregnancy and delivery, and now she's a perfect mom with a perfect baby. Yes, I sound jealous because I am.

But I still made an effort to check in on her, even though she didn't check in on me during my miscarriages or my divorce. And now she says I wasn't involved enough and that she doesn't accept how I treated her, and that my miscarriages don't excuse everything.

Frankly, I'm disappointed. I mean, if I had ignored her, OK, but did I check in on her? What was the minimum for her was the maximum for me, and her reaction really hurts me...

Has this ever happened to you from a sister?
