Recently, I was talking with someone about how hurt they felt by a person. Many times, as followers of Christ, we end up finding our joy through people. We will never be satisfied when this happens. Check out what my response was and hopefully it will help you see clearly how to remedy this issue.
Sounds like you are hurting pretty bad. But I know the reason you are hurting bad. When you put so much reliance/happiness on a person you will always be failed. Humans will always fail you. Not because we are inherently evil but because we are selfish.
My suggestion would be to put your focus back on God. Through that you will depend on only Him and He will always comfort you. 1 Peter 5:7 says “Cast all your anxiety on Him because He cares for you.” Also if you go to http://www.usfbcm.com/refuel/?page_id=69 there are some prayers based upon Scripture that will help you focus on God more than yourself. But this can only happen if you trust God. So read your Bible daily to renew your mind on Him (Romans 12:1-2).
What would you say? Would you add anything?
