True love is from God. How is your love life? How do you treat your fellow man? Are you selfish?
Is your love dysfunctional? Do you struggle in your relationships?
You may be aware of your weakness when it comes to loving another person. You may struggle with control issues or trust issues. Can you trust God? Do you have a relationship with God? It begins there. If you have surrendered to God's Word and trusted in  salvation through Jesus ,His Son, you have within you the capacity to love others. You already naturally love yourself; that is a given. But now you must love others the same way you love yourself. Impossible without God's help.
