Am I going to hell? (only for Christan's)?

I was a "lukewarm" Christan. I lied to others who I really was. I told many people I was Muslim I tried to even be muslim, but I couldn't leave Jesus. While I was learning about Islam I started to doubt God and I want to convert to Islam, but I was scared because I knew Jesus was God. For like a day I did stop believing he was God and converted to Islam, but I went back to Jesus and repented for what I have done I really was sorry. I never called god evil or worshiped the devil. I always knew Satan was evil. I do worship God with all my heart and talk to him. When I was little I did think God hated me and believe he was a racist, but I think that was the devil trying to pursued me to think that because I was trying my hardest to resist those thoughts. I have converted my best friend to Christ. Did I blasphemy against the Holy Spirit? My bond with God is getting stronger by the day and as I pray more I see Him work miracles and worship him for it. Will I ever be forgiven for what I did? What exactly is blasphemy against the Holy Spirit? Is it something that you can just sit down and do, or is it a long term thing that you have to constantly do? Was what I did blasphemy at all? Please help I'm worried! I just want the truth!
