Please pray for my relationshp

I love my boyfriend, but I fear I am struggling with both anxiety and lust. I am constantly dreading something bad will happen to him or us, and it ruins my ability to be present and enjoy one another. With this fear, I have brought myself to commit sin by lusting over him and feeling I must connect with him physically to get him to stay despite my anxiety. Lord, I pray that you take away my anxiety and help me with self-constraint to stop this cycle of sin. Please pray for me and us while I try to manage my anxiety to honor God, better myself, not self sabotage my relationship, and remove blockages from our relationship. I just need to let this go and trust God. In Jesus name, Amen.
