god's favourite even though all i do is sin

telling me stuff before it happens, giving me literally everything ive wanted for years
i told someone i thought i could trust (a christian) but they said said its not god. said it’s something else, something evil
why would they say something like that?

It sounds like a deeply personal and spiritual experience. Their response might stem from their own beliefs or fears. Some possible reasons:
1. Fear of the unknown or supernatural
2. Protecting you from what they perceive as evil
3. Upholding their religious beliefs
Consider having an open conversation to understand their perspective

not christian but a muslim belief is that it can either be gods blessings or a test from god. to see if u take what ur given for granted by sinning even after being blessed

Feeling rewarded with everything you want for perpetual sinning with no intent to change doesn't sound much like God, that sounds kinda more like the other team. Most Christians would just think you were taking the **** really.

"it's not that i don't want to, it's that i can't really change my nature."
A good realisation, the apostle Paul had it after he received God's Spirit, giving him access to God's nature (Romans 7:7-8v2)
This is why Jesus said "you must be born again (from above) of The Spirit" (John 3v3, 5).
You must call on God to do this, I and all my friends have.
Your roots (religion) didn't hold you and enable you to change and be what you would want to be, this will.

but i like men, cant change that ; ////

Again, true but God can and has, your choice

but i already knew, even as.a kid, it was never a conscious choice
i dont think theres anything i could do to stop being like this

Correct, so, how much do you want to see what God can do?
"Eye has not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
But God has revealed them unto us by his Spirit: for the Spirit searches all things, yea, the deep things of God." (1 Corinthians 2v9-10)

if he wanted to, it’d have happened a long time ago i think

God doesn't impose his will on non-believers or people why choose their own ways
