Ending my friendship with my childhood friend!

Hello Ladies, I need to vent like NOW! Yesterday my best friend of 18 years called me and said some pretty hurtful crap!

I'll give you a quick recap! My bff has 4 children with one on the way and I have one child. I've been trying to conceive since 2014 but it's just not my time yet and I'm ok with that. My bff has been depressed and I've been there for her every step of the way. Our entire friendship I've always looked out for her. Whatever she needed I always had her back.

Yesterday she had a doctor's appointment to find out the gender of the baby. How exciting right? Wrong!!! She calls me and she's clearly very upset. She starts off by saying she's upset and after she tells me how she feels she doesn't want to talk to me for a long while. I'm like oooookkaay what's your deal!? She tells me I found out the baby is a boy! So I start shouting out sounds of joy! She then goes on and says he has Down syndrome. I was shocked but I instantly began to comfort her and let her know everything is going to be okay. A quick side note: ive worked with children and adults with special needs for 10+ years and I LOVE IT! So anyways, she fixed her lips to tell me she knows I put the evil eye on her baby along with other people who aren't happy for her being pregnant. I was taken back, like I literally almost fell! But she wasn't done...she then tells me she knows i put this evil eye on her unborn child because I'm not able to have kids!!!! WHATTTTT!!!!!! Omg I lost it!!!!!!! my best friend really just said this to me!! She stated she knows I'm jealous that she's fertile and the jealousy I have for her baby is the same as her being jealous that I have a nice house and it burns the f*#k down because she's in a shelter!!! I'm like what the hell are you talking about. At that point I was so upset and so hurt. She then hung up on me which really pissed me the hell off. Please someone tell me wtf was that!!?? I understand she's upset and shocked but omg you take it out on the one person who's had your back through thick and thin no matter what never judged her or anything. And what hurt me the most were the things she said to me not being able to conceive. Granted my doctor never said I can't I just have irregular periods but there's medication I can take.

This isn't the first time she's done this to me either. In 2010 out of the blue she called me and said being that she's Muslim we can't be friends because I won't convert to Islam and she wants to surround herself with other Muslim people. Fast forward two years later 2012 she messaged me on fb and apologized. She's still Muslim by the way which doesn't affect our friendship or how I feel toward her. But this evil eye stuff really twisted her brain! I need some feed back from you ladies!
