tbh, its neither good nor bad. growing up, i had someone i was constantly comparing myself to (with grades, looks, weight, relationships, etc.) and that sucked. People always confused us and we only just recently grew out of the grouped nickname “the girls” and “the twins” by family members. People who met us at the same time assumed that they had to befriend both of us to be fair and to keep things from getting awkward. In those ways, it sucked. But on the other hand, i got to grow up with someone who went through almost everything with me. She understood me more than anyone else ever could, and it was always reassuring to have someone in my life who knew exactly who i really was. when the worst of the worst came around, i always had someone to understand and help me through it.
