What are some open minded denominations?

I’m looking to get back into faith again. I was a Christian a couple years ago but fell out of it because I was not acting godly whatsoever. I’ve done plenty of things that I would consider sinful.

Such as having an abortion. I also am bisexual. Are there any denominations of Christianity that would accept who I am and my past? I want to start going to church but have no idea where to start. I’ve heard denominations such as Mormonism and Jehovah Witness are super strict so I don’t think I’d fit in there.
