I got to a point where when I pray I overthink it too much and now feel like I'm lying to myself. I get so much doubt about if what I believe is real and now I feel like I csnt pray properly. it's been like this for so long.

If you are Christian- what helps me is Matthew 6:7-8 and especially Romans 8:26. God knows our hearts and our truths from fleeting thoughts and feelings. He knows what we need and the Holy Spirit translates where we fail to “pray right.” So we don’t need to!
