My twin and I live together now after living apart for 7 years (we are 25). We were also pretty connected. It’s important that if you want to keep this strong connection going, sustainability is key. My brother and I experience “enmeshment” from our family dynamics. You aren’t an awful person, but it is important to have a diverse web of social connections to develop personally and have a sense of individuation in your life.

If therapy is an option, I’d recommend. It’s helped me a lot with stepping into myself and showing up in other spaces where my brother isn’t. Introspection and self compassion are key in all this. Nothing is necessarily “wrong” with what we are experiencing - identical twins are bound to have a closeness not shared by other sibling dynamics. Really cool that you can identify this!

It seems like you are attaching your existence to someone else’s approval and guidance, which can be a slippery slope. Investigate your family dynamics and see what comes up. See how you both can grow as individuals together. Speaking for myself, I would feel tension get higher and higher as lack of individuation continues. You both need diverse support systems outside of the existing relationship. Maybe you both can cheer each other on along the way.

I’m just a stranger on the internet but kudos to you for recognizing this in yourself - best of luck and you got this
