Hi Nicky, in times like these it's a good thing to stop, look at how you respond to people who give you a hard time and in your heart, how do you respond. With love or anger. Many times we slide into thoughts about other people and things that irritate us and we think bad thoughts. Normally, we don't respond that way but we think that way. Our thoughts can be our enemy and get us in trouble with the Lord. I'm not saying that this is your problem, but folk that I have counseled, it was.
How do you get back to a good relationship with Jesus? So you can rededicate your life and have it stick? You can do what I do every morning. I greet My Heavenly Father, Master Jesus & The Holy Spirit with a "Good Morning". Then I say to Jesus, "Master Jesus" I surrender my life to You this morning, I surrender my heart, my mind, my thoughts and my body to you. Please perfect the things that are lacking in my heart & mind". Let me tell you, if you keep that up every morning, in a year, or sooner, you will be a different person! I promise.
Generally, when we feel a distance from our Father, and Jesus, we are the ones who have drifted away, not God. So repent of any known sins, ask forgiveness, and get up and start over. Jesus love you, forgives you, and will give you the strength to go on. He not only is the God of second chances, but 3rd 4th 5th 20th 50th and well you get the picture.
