was I raped and did I make too much about it?

Clearly you were raped.

Your mental and emotional health can be impacted unless you learn to cope with this experience in a "healthy" fashion.

Your family's religious mindset is what it is, yet - chances are pretty good that you could use some professional help learning to cope with what happened.

There's no shame in being gullible - and you didn't deserve to be raped. You didn't cause it, nor could you have controlled what happened, since you were drugged.

I'd strongly encourage you to consult a mental health professional, sooner than later - as the rest of your life depends upon your ability to cope with this situation.
