I don’t know if this will help or not but here is a prayer for protection:
**
**O My God, I adore Thee **
**and I love Thee with all my heart. **
**I thank Thee for having created me, **
**for having made me a Catholic **
**and for having watched over me this day. **
**Pardon me for the evil I have done this day;
and if I have done any good, **
**deign to accept it. **
**Watch over me while I take my rest **
**and deliver me from danger. **
May Thy grace be always with me.
**Amen.
