Hi, I’m an identical twin and my sister and I have separated before but it was only for 2 weeks and even after that when we saw each other again we broke down in tears. I want to chose the college I have always wanted to go to but it puts me far away from her. Any ideas on how to make this separation process easier for the both of us?
Normally I’d suggest you start separating your lives now so that if you choose to go different directions this fall it’s not a cold turkey hard parting. That might include jobs in different places, exercising apart and that sort of thing. But with C19 you’re really limited in your options for getting out of the house. Maybe you could try to do little things like not doing homework together to explicitly force some gaps in your lives. It sounds dumb and contrived, but the awkwardness is part of what you’re trying to get a feel for.
My best friends are identical twins. I met one of them at college (they went to separate colleges) but you don’t become friends with one without becoming friends with the other. 
We are now in our 50s and still very close. One went to a small LAC in New England; one went to a large big 10 university. Please choose the school you want to go to. You won’t live your whole lives with each other (both of my friends are married with children) but they are still incredibly close and involved with each other. I agree with the poster above - start finding things to do separately and get used to the idea of operating alone.
