If all we have ever known is conditional human love, why would we expects anything different from self love?

Self love isn't supposed to be hedonistic. Nor is it supposed to be conditional. This is why self love needs to be experienced through a higher power. Allow God to show you how wonderfully made you are. Love isn't blind. Love sees all and chooses to love anyway. 

I hope this helps you in find unconditional love in someway.
