You made a few points that are worth mentioning:
"Many books say that one goes to hell if they convert religions. But I'm not sure if I fall under that category, because I never accepted Islam in the first place maturely"
I'm not sure what books you are referring to, but the Qur'an is what we follow in Islam. What you may be referring to is apostacy, which in this case would be abandoning Islam, after have being muslim.
You say that you were never a muslim in the first place, so how could you be punished after death by going to hell? Don't deceive yourself. Even if you didn't convert, you are a disbeliever. You have taken Jesus, peace be upon him, as your God, whilst in Islam, this is detested. Jesus was no more than a prophet of God. He commanded the people to worship God.
Proof of this in the Qur'an:
“O People of the Scripture (Jews and Christians)! Do not exceed the limits in your religion, nor say of Allaah expect but the truth. The Messiah ‘Eesa (Jesus) son of Maryam (Mary) was (no more than) a Messenger of Allaah and His Word (‘Be!’ – and he was), which He bestowed on Maryam, and a spirit created by Him; so believe in Allaah and His Messengers. Say not: ‘Three (trinity)!’ Cease! (it is) better for you. For Allaah is (the only) One (God). Glory be to Him (Far Exalted is He) above having a son. To Him belongs all that is in the heavens and all that is in the earth. And Allaah is All-Sufficient as a Disposer of Affairs.”
4:171
And yet again:
And surely they disbelieved when they said: 'Christ, the son of Mary, is indeed God'; whereas Christ had said: 'Children of Israel! Serve Allah, Who is your Lord and my Lord.' Allah has forbidden Paradise to those who associate anything with Him in His divinity and their refuge shall be the Fire.
(5:72)
And yet again:
“… But those who disbelieved will have a drink of boiling fluids and painful torment because they used to disbelieve.”
[10:5]
And yet again:
“… Then as for those who disbelieve, garments of fire will be cut out for them, boiling water will be poured down over their heads.”
[22:19]
And yet again:
“Surely! Those who disbelieved in Our Signs, We shall burn them in Fire. As often as their skins are roasted through, We shall change them for other skins that they may taste the punishment. Truly, Allaah is Ever Most Powerful, All-Wise.”
[al-Nisa’ 4:56]
“If only those who disbelieved knew (the time) when they will not be able to ward off the Fire from their faces, nor from their backs; and they will not be helped.”
[al-Anbiya’ 21:39]
"I'm not sure what I am asking posting this but I just thought that I would share it as I was scrolling throught the spirituallity forums."
"But I guess what I am worried about is what my relationship with my family will look like when I reveal to them that I don't follow their religion."
Now, to conclude, what I have mentioned above is not to force you back to the Truth. Rather, as you know, you have free will to do as you please. Every action in this world has a consequence, which is either good or bad. I have cleared the stance of my religion on you, as you seemed unsure as to what you may be held accountable for in the next life. Whether you believe or disbelieve, I have no worry.
Your family would be disheartened, this there is no doubt. However, if I was your family, I would understand that it is rather your loss. Islam, as the fastest growing religion in the world, will continue moving on, with you or without you. With me, or without me. People are reverting to Islam in masses, from the standard civillians to the celebrities. Islam will keep moving on.
This is a choice you have made at the end of the day. I will finish this with a verse where Almighty God says:
“Say to those who have disbelieved, if they cease (from disbelief) their past will be forgiven. But if they return (thereto), then the examples of those (punished) before them have already preceded (as a warning).”
[al-Anfaal 8:38]
