>and I don't want to lose them
Something to come to terms with in accepting Christ is that we must be prepared to lose all for Him, even our own life. See also Matt. 10:35-38
>or have every conversation become a heated argument.
Here I would advise you to bide your time and slowly start learning by reading, watching vids etc. on introductory topics, doctrine, apologetics, etc. with a view to establishing and being half confident with 3 things:
1) the existence of God
2) the reliability of the new testament (i.e. that
a) Jesus of Nazareth was a real person who lived and had a 3 year ministry
b) was who he said he was i.e. the Son of God and the Christ told of in the prophesies of the Old Testament
c) crucified on the cross and buried in the tomb
d) that on the third day the tomb was found empty and that his followers believed they saw the risen Christ following his burial in the tomb) and
3) that the most reasonable explanation for the ressurection claimed in the gospels is that Christ really was ressurected
Once you have these locked down, even if you don't believe it yourself yet, you'll at least be able to explain to your family the reasons why Christian's believe what they believe and that it is actually fairly reasonable in most instances, and certainly isn't blind faith. Some resources for this below.
>Next, it feels like such a huge undertaking to really "get" Christianity.
It is, I'm a little younger than you and had my admittedly poorly-developed faith reasoned out of me by my unbelieving friends as a teenager, and I've spent the past couple of years looking into this stuff before I felt I could commit myself, concious that I wanted to understand what it is I'm getting into and, per 1 Peter 3:15, give a reasoned defense.
Secondly, as well as the three points above as to understand it is why Christian's believe what they believe, you must understand the basics of the faith themselves. That is, who Christ is, who God is, what his character is and attributes are, what Christ achieved on the cross, why it was necessary and it's the best thing ever, who we are, what this world we live in is and what has happended to it, and owning up to our responsibility for the state of it and our responsibility to each other. If you haven't got their already (which you may have, I don't know), understanding these things should lead to one thing: Repentance.
>I'm decades behind everyone my age.
Irrelevant if you're willing to seek the truth.
>When I hear people pray and speak about their experiences it's like they're using an entirely different language that is confusing and honestly seems kind of "culty" sometimes.
I can definitely appreciate what you mean by this, I thought the same as an atheist and am sure my language puts off my friends to some extent now when I try to set out what it's all about. But like I said take your own time and become accustomed to what it's all about first off by doing your own research.
>The few times I've been to church I've felt like an outsider/imposter (and been treated like one by the impenetrable cliques everyone has formed).
That's a shame, maybe check out a few other churches in your area if there are more.
>Next, I've never had a religious experience
No problem
>I just feel drawn to Christianity for some reason (and I'm not even sure that's a good enough reason to convert).
Probably not on it's own no. Definitely good enough reason to take the time to look into it more
>I've tried reading apologetics but it quickly turns into philosophical semantic debates far removed from the mystery of God and faith.
Apologetics is a reasoned defense of what we believe, explaining clearly to non-believers why and why it's reasonable. The idea is to clarify so it is certainly a separate aspect to meditating on the mysteries, of which there are some in Christianity. If the resources below don't pique your interest, which arn't necessarily dicrect apologietics but will certainly help you see why we believe what we believe, then I guess it's down to you where you go from there.
