It's so understandable you'd be angry with God. I say don't feel bad about feeling that way. God understands and can handle it. You need to process how you feel in your own way.
For me, my abuse was done by someone outside of the church, and it was people within the church who helped me. My experience prompted me to want to go to Bible college because I wanted to pay forward the kindness that was shown to me.
The theological question of why God allows evil is addressed by a topic called Theodicy. If you really wanted to explore what theologians and philosophers have constructed, you could do an online search for that term. To be honest, I never heard a theory or explanation during my studies that resonated with me. The topic merely justified to me why some people are atheists, rather than the usual "atheists don't believe in God because they prefer sin" rhetoric.
I did become an atheist in Bible college due to some issues unrelated to the problem of evil/suffering. About 15 years later, I gradually came to believe in a higher power and now very loosely identify with being a Christian.
I am now reading the Bible with a completely different perspective, reading it with an open heart, and not from my analytical brain. I recognize that the scriptures were written in a different language and within a completely different context. The majority of what I have been taught about the interpretation of scripture could possibly be wrong, so I am letting scripture speak to my heart. The messages I am hearing in my heart are much different than what I've been taught in church and Bible college.
I have tried to find meaning in what happened to me. I found an explanation within myself that resonates with me, that might not line up with what the church has taught me, but it's my inner truth...
What I am about to write does not mean I condone abuse. It is how I personally found meaning in my suffering.
As crazy as this sounds, I believe that before I was born, I chose to experience life in a way that could potentially subject me to the abuse I experienced. I wanted to take that risk so that I could learn forgiveness and healing. I believe as heinous as the abuse was, it was that suffering that made me so kind-hearted and empathetic. I never knew I could forgive my perpetrator but I did. I'm now in the process of healing and writing a book based on my experience with PTSD that I think will help others.
You have every right to be angry. Anger is considered to be "a higher vibration" emotion than helplessness or depression, so you've got that going for you. Anger is also referred to as a secondary emotion. It's the response to another underlying emotion. So the abuse may have caused a certain emotion and because of that you feel angry. What is the underlying emotion?
Anyway, for me personally, being completely stuck in my head and analyzing difficult questions had their place in my journey but could only take me so far. After a while I realized it was better to follow my heart, not my thoughts. The thoughts and analysis were often a distraction from giving my heart what it truly needed. I sometimes had to tell my mind, "Good question. It's okay that I don't know the answer right now" and to cater to my wounded heart instead.
