A shark attack victim learning how to walk again. It's a struggle to return to normal life – not just for one Hawaii man, but two.

25-year-old surfer Colin Cook has been at Queen's Medical Center recovering from Friday’s shark attack and working to become mobile again. The attack happened at Oahu’s North Shore where a shark bit off the lower part of his leg – and doctors had to amputate more.

Family members say even though he is struggling to get his pain under control, he is still in good spirits.

According to his cousin, Cook hasn't seen the news footage of the attack, but he is aware of the outpouring of support.

Those in the surf community have also been reaching out – offering to bring him food and clothes. There is even an effort to help keep his fledgling surfboard shaping business afloat until Cook can get back to work.

Along with people in Hawaii pitching in, calls, prayers and contributions have come in from around the world.

A GoFundMe page to cover the cost of a prosthetic leg has been set up and is close to its $50,000 goal.

It’s an important part of Cook’s recovery because even days after the shark attack he has told family members he wants to surf again.

And he’s not the only one recovering from a shark attack. Braxton Rocha also had his leg mangled after being bitten by a shark while spearfishing off Upolu Point.

“I thought I was going to lose my leg. I thought there was no way I was going to keep my leg, but I still have it. It's a miracle,” said Rocha.

Doctors had to staple him back together, and though he still has a trouble walking, he has been slowly regaining strength. Rocha hopes to get back into the water in a month or two.

Despite suffering a brutal attack, he doesn’t want people to hate sharks but rather to respect them. He also adds that the whole experience has made him more grateful for each day.

"After my shark encounter it open up my eyes, life is too precious, you know."
