If I may, I don’t think that the Student Room is the place for this. If you are set on converting to Christianity (and understand and accept that your family may neither understand nor accept) then the proper course is surely to approach the university chaplain or the clergy of the denomination you choose to join.
In the Roman Catholic tradition and in the Anglo-Catholic parts of the Anglican tradition, we don’t emphasise an emotional conversion but the study of religious belief (the “catechism”, or “taking instruction”, usually now a course of lessons rather than a literal question-and-answer book to learn by rote) and the priest will decide—usually after a good bit of time—when you are ready for baptism, confirmation and first Holy Communion.
You would be more than welcome at services even now though not to take communion as you very probably aren’t baptised — it’s generally done that you can come up to the rail with your hands crossed over your chest and the priest will bless you instead.
I wish I knew more about the evangelical denominations of Christianity but I cannot advise you there, only to be extremely careful of small or overseas churches with extravagant claims of miracles, claims of wealth or success for adherents, stories of speaking in “angelic tongues” (glossolalia in medical terms) or healing by faith. I don’t know of any respectable cleric who believes in such things.
My genuine concern is that you mention that you were “forced into the hijab”, the veil? I hope you know that in Britain nobody has the legal right to make you as a an adult woman wear something that you don’t want to!
If there’s an element of coercion in religion in your family or community you need to be careful, make sure you are safe. Sadly religion of all kinds can bring out the worst as well as the best in people. There are many regrettable passages in the history of the Christian church as well.
I will pray for you, but I don’t think that a student forum is the place for deep questions of faith. You don’t know who I am, or what angle I might have.
Nor is the Internet a place to learn about it, it has to be lived.
I hope one of the more mature forum members will pick up on this thread.
Most of all, stay safe!
PS If you are an agnostic in the technical sense of the word, you don’t know whether a God exists or not, I do have to warn you that a priest or vicar couldn’t baptise you in good faith.
The question surely would be — I believe in one God, but I now I think I believe that Jesus of Nazareth was God Incarnate and the Saviour, not the mortal human but righteous Prophet Isa as the Koran teaches? Of course, this would seem to imply that you also no longer believe that Mohammed is a prophet.
Please be very sure and take advice from those better qualified than I. There’s no shame in simply leaving those parts of Islam you find oppressive and living in the world, attending a few Christian services, making friends of all faiths and none. If you truly believe that there is a divine purpose for you then you will find it.
