Pregnant friends while grieving a miscarriage

I’m grieving my miscarriage, but struggling with my friend group. I have three very best friends who are all due within weeks of when I was due. I’ve been avoiding being around them, and even texting with them is a trigger. Its been a month now, and I still can’t. It’s horrible- I just want to be okay, and I want to be able to be there for them during this exciting time. I’m not able to do either. My plan is to hide out in a cave until we get pregnant again... anyone have any words of wisdom or been through this?
