It's been five-and-a-half months since six Irish students lost their lives in the Berkeley balcony collapse.

Survivor Clodagh Cogley was one of seven friends seriously injured in the accident, but last night her family shared an extremely positive update about her health.

"Clodagh has now returned to university in Dublin," the post on the 21-year-old's GoFundMe page read.

"She resumed her studies initially while continuing to receive in-patient rehab hospital treatment.

"We're pleased to tell you that she's also now moved back into her family home."

Clodagh, who is a Psychology student at Trinity College Dublin, suffered a broken spine, broken knee and shoulder, two collapsed lungs, and five broken ribs in the fall.

"Solutions to adapt the family house are nearly completed so that she may resume a normal life," the post continued.

Clodagh herself posted to Facebook shortly after her accident to let friends, family and the public know how she was getting on.

"[T]he chances of me using my legs again are pretty bleak… Not the best odds but I'm moving to a great rehabilitation centre here in San Francisco for two months," she wrote.

"Who knows maybe legs have been holding me back all these years and I'll realise my talent for wheelchair basketball."

Since the accident, over €100,000 has been raised in Clodagh's honour to cover medical funds and the adaptation of her family home for wheelchair use.

Eoghan Culligan, Nick Schuster, Lorcán Miller, Eimear Walsh, Ashley Donohoe and Olivia Burke were all killed in the tragedy, which saw the balcony they were standing on in a Berkeley student apartment collapse.

The group had been celebrating the 21st birthday of Aoife Beary, one of the seven injured.
