Being worthy just because I am me

I am struggling to believe that I am worthy of anything just because of the simple fact that I am a living, breathing human being. That sounds so crazy to me.
I truly believe that I have to earn things or do something to deserve them before I can accept anything.
This is true for money, love, health.
I believe that I have to behave a certain way or do something in particular to earn anything that I get.
How do I start to unravel this mess?!
