Has God given up on me... completely?

I'm a 16 year old girl from Arkansas... I'm terrified I am going to hell and theres nothing I can do about it. I have accepted God as my savior... I trusted him... but I have felt nothing from him in far too long. when i was 11 i got so mad i swore myself to the devil. it was the stupidest thing i ever did in my life. i prayed for forgiveness the second I did it and still do... but i feel like got gave up on me right then and there. I do love god. I just feel like I've lost a father. I got suicidal for a while because of these thoughts and felt like there was no hope... I would love some answers to help me... and not just to reassure me. I want the truth please.
