You aren't the only one to experience fear like this...
I grew up in religion where the fear of God was taught way more than the love of God.
I rejected the biblical God because of this, among other experiences.
When God called me out of the world, it was first by love and when I ignored him, he didn't mess around.
Although now I'm starting to slowly realise everything he has done in my life once I got saved, has been from love - it hasn't been easy and I've had the same question. But remember if a thought you have ever begins with 'What if...' and sows a seed of doubt about God, who he is and what he can do: this is from the enemy.
Here is some scripture that directly answers your question:
1 John 4
7 Dear friends, let us continue to love one another, for love comes from God. Anyone who loves is a child of God and knows God. 8 But anyone who does not love does not know God, for God is love.
9 God showed how much he loved us by sending his one and only Son into the world so that we might have eternal life through him.
10 This is real love—not that we loved God, but that he loved us and sent his Son as a sacrifice to take away our sins.

18 Such love has no fear, because perfect love expels all fear. If we are afraid, it is for fear of punishment, and this shows that we have not fully experienced his perfect love.
