Only God can fix the issues of our hearts. Once we allow Him to heal our hearts, life becomes easier. The reason I know this is because Jesus said, "Do not let your hearts be troubled. Trust in God; trust also in me" (John 14:1). Anything that Jesus says is true, right? Right. Don't allow anyone to trouble your heart. Keep on trusting that God will work things out for you. The Bible also says, "Above all else, guard your heart for it is the wellspring of life"  (Proverbs 4:23). In addition, keep in mind that you cannot put your trust in your heart. Your heart can deceive you at times. Remember when you were younger and you thought you just loved so and so with all your heart? Was your heart correct? Nope! "The heart is deceitful above all things and beyond cure. Who can understand it?" (Jeremiah 17:9). Therefore, put your trust in God.
