There are two versions of this answer.
One relates to conditional love. If God has certain conditions which must be met in order for you to be worthwhile loving, then if you don't meet those conditions you aren't worthy enough. This makes you think that in order to become worthy you have to meet certain conditions, or turn yourself into a more lovable person. And also you believe that if you aren't meeting certain conditions, this PREVENTS God's love.
But then there's unconditional love. If God loves you unconditionally then it doesn't matter what your current state is, or what you think you did, or whether you're awake or sleeping. God is loving you 100% regardless. This means he must be overlooking everything you think would keep you from Him, and instead sees the REAL YOU.
Being worthy of God also means that God wants what you are or what you represent. It means God shares the view of you that you have of yourself. And it also means that your worthiness is lofty enough to be attractive to Him.
When you believe you are unworthy, it is a form of denial which attempts to shut God out, because if you didn't, you wouldn't be able to believe you are unworthy. So you have to pretend you're not. But it is only pretend. You can never be ACTUALLY unworthy, you just think you are.
Also to be worthy of God means that God values you and wants you and welcomes you. If you think there's something about you that proves that God wouldn't love you, maybe you're too ugly or have too many grievances or don't like your job or whatever, maybe you hold this up as the reason why God wouldn't love you. But it isn't proof. It's a mistake. And it is an incorrect answer.
God can't stop finding you worthy because God is constantly creating you, choosing you, sustaining you, loving you, extending you and protecting you. You came FROM God, because He decided he would extend love, as love, as you. Your very nature, your foundation, is love. If you came FROM God then obviously you ARE what God wants, because God wouldn't be in the business of creating something he doesn't like. He only creates with love. So you must be lovable.
Your belief that you're not lovable is the only problem. You think there's some reasons why God doesn't love you. None of those reasons are the truth and none of them have the power to stop God's love. You think they can, but they don't. You can hate yourself to death but God still loves you. And then He's like, ok, are you done playing now? It's time for dinner.
