Friend is pregnant with twins

Hi all!! My best friend is pregnant for the 5th time and is 20 wks in...literally just found out a few days ago that it was actually twins. Truly shocking.

Anyways she is outta her depth and having a lot of anxiety issues right now. She is also in unbelievable pain because of the extra strain on her body. I want to help her.

What are some ways or products she can use to help relieve the pain and potentially help with the anxiety?? Any recommendations are welcome!
