i struggle with anxiety too. right now i’m doing a monthly challenge “renewing the mind” and i find devotional on the Bible app to help me learn what it means to renew my mind and how. for the entire month i study the Bible, pray, find supplemental material like podcasts, songs that speak to me during this season and i begin to walk in what i learned. maybe this can help your mom a little bit. as for you, i was here with my prayers not to long ago. it felt like my words were reaching the air and then destroyed and never reached God or that they hit a wall. but i prayed for God to reveal himself to me again, he did, and then my prayers felt like normal again. i believe if you ask him to reveal himself or encounter you again, he will. your prayers are still reaching him, sometimes it’s our own feelings doing this. so when you pray try to be aware of his presence if you don’t already. i’ve prayed for you but i hope this helps a little bit!
