When she stood on her new prosthetic leg for the first time May 29, Boston Marathon bombing survivor Adrianne Haslet felt her eyes fill with tears.
“I started crying,” the professional ballroom dancer, 32, tells PEOPLE. “I hadn’t even taken a step yet. Just to stand tall was extremely emotional.”
In this week’s PEOPLE cover story, featuring candid interviews and an exclusive photo portfolio taken on May 30 at Spaulding Rehabilitation Hospital in Charlestown, Mass., Haslet and 10 other survivors – including nine amputees – reveal how they’ve been coping since the April 15 blasts that claimed three lives and left as many as 264 people injured.
