First of all, sorry that your friend has treated you like that, it is not a Biblical view on how we are expected to treat others. Never has the Bible advocated forcing our beliefs onto other people and it is sad that a large swath of Christians have been doing it.
We are all sinners, we all need Jesus, God loves everyone be you straight, gay, black, white, old, young, male, female, other. We are also called to love everyone, even those we disagree with, even those who hate us.
I love my LGBTQ+ friends, and I hope they feel the same towards me.
I personally think that homosexuality is not right for me but I don't force that onto others. Someone might think that eating meat is wrong for them but you would still be friends with them right? Again it would be wrong for them to try and push their "don't eat meat" values onto yourself especially said not to. Tolerance is only possible with those you disagree with (by definition) you can love someone and be friends with them without agreeing with everything they do, we do so all the time.
One good book on this subject to see the biblical view is "Is God anti-gay" by Sam Allberry https://www.amazon.com/God-anti-gay-Questions-Christians-Ask/dp/1908762314
Good book, written by a gay Christian
“Is God anti-gay?” By Sam Allberry.
Also, keep talking and seeking God and let the Holy Spirit lead and teach you. Do not make being gay the biggest concern on your radar. Sometimes there are bigger issues that God wants to talk with you about or work with you.
“He who has begun a good work in you will continue it…” the book
Good book for you that isn’t about fixing, but is about being comfortable as a SSA chaste believer: https://www.amazon.com/God-anti-gay-Questions-Christians-Ask/dp/1908762314/ref=mp_s_a_1_3?dchild=1&keywords=does+god+hate+gays&qid=1617514990&sprefix=dows+god+hate+&sr=8-3
I’m a pastor and welcome any through the doors of the church. I don’t care what you’ve done, if you’re willing to “repent” and “go and sin no more,” than you have a place in the body. If you want to change the church to allow your flavor of sin, we’re gonna have a talk. That’s what the Bible tells us to do, so that’s what I do. Love God and Love People.
Praying you have an amazing Easter. Don’t forget the resurrection is for you!

I’d add Sam Alberry to the list:
Is God anti-gay? (Questions Christians Ask) https://www.amazon.com/dp/1908762314/ref=cm_sw_r_cp_api_glt_fabc_P0PWH8AXGHS0AH907AF8
Got a book for you to read. Sam Allsbury is a chaste same sex attracted Anglican priest. His book is worth reading. https://www.amazon.com/God-anti-gay-Questions-Christians-Ask/dp/1908762314/ref=nodl_
I want to recommend two books to you which defend Christianity's 'traditional' interpretation of homosexuality.
Is God Anti-Gay? and The Plausibility Problem
Both are written by same-sex attracted men who have chosen to remain celibate due to their understanding of Christian teaching.
I completely understand where you're coming from. I strongly recommend that you start listening to the voices of Christian pastors who stay faithful despite their same-sex attraction. If you find it a struggle, imagine what it's like for these brothers. Last weekend, I heard a (gay, Reformed) pastor say: "I sometimes walk into the room wondering whether I'm the liberal or the conservative. Then I get shot at by both sides anyway."
Living Out is an excellent online resource. I knew several of these men in the past and everything they write conforms with how I saw them live.
Is God Anti-Gay?: I'm half-way through this. I wouldn't give it to gay friends but it's purpose-written for your situation.
Washed and Waiting Personal reflection that really challenged me as a het cis brother.
Same-Sex Attraction and the Church, on Kindle under its British title, The Plausibility Problem. I haven't read this, but heard the main points direct from the author. It's a challenge to Reformed churches (well, evangelicals more widely too) to repent of our past failure to live in a way that would make us the safest place for LGBT+ people, as we should be.
Out of a Far Country This is a dramatic story that left me with some unanswered questions. However, I take it that you're in the US and this is another American testimony.
Here is another good read: https://www.amazon.com/God-anti-gay-Questions-Christians-Ask/dp/1908762314
I don't want to be 'that' guy, however you cannot scripturally justify engaging in same-sex relationships and sex.
I am a bisexual teenage Anglican like yourself. It is important to note that same-sex feelings are OK. They are not a sin, nor evil. But engaging with those feelings is a sin and cannot be scripturally justified. It's these reasons why I remain celibate, and don't allow my same-sex feelings to control me or define me: those thoughts come, and I let them go.
Is it the worst sin? No, it's not. But by having a same-sex relationship, you are engaging in sin; no amount of 'Jesus loves me!' can change that. Jesus does love you. God loves you; you are a son of God like anyone else. But like any Father, our Father in Heaven has rules, expectations and guidelines; when we stray from this, and start to say 'It's okay, he loves me!' although you're right, you're also justifying something contrary to the word of God.
Sam Allberry, a gay Pastor, did a much better job explaining this than I ever could in his book - 'Is God Anti Gay?'. It's a little book, but you can buy it here. He speaks about his personal experience, how to approach this issue as a Christian, and speaks directly to people like yourself who think it's Biblically OK. Fantastic book.
