When I was a teenager, I didn't feel like I had an identity at all. I was a bundle of trauma, loneliness, undiagnosed autism and unrealised transness. I barely communicated in the "real world", spending all my time with online communities and friends that spanned a gamut of abusiveness. I "came out of my shell" when I started doing youth theatre. I became more social, began to have an identity in the commonly accepted sense.
This time, I think I've really cracked the code.
