The 29-year-old 1500m runner suffered a problem-hit build up to the London 2012 Olympic Games, first picking up a hip injury then being diagnosed with blood clots on her lungs.
That plunged her participation at London 2012 into severe doubt however, just over two months after beginning to run again in May, she was selected onto the British team.
At the Olympics Dobriskey impressed to make the 1500m final but was a distant tenth as Turkey's Asli Cakir Alptekin won gold, something she looks back on and wishes she could change.
Dobriskey will get the chance to test her early 2013 form in the international invitational 3km race at the Great Edinburgh Cross Country on Saturday and is determined to have no regrets this year.
"2012 was a tough year. I'd always imagined it would just click and go my way, I couldn't have been more wrong," said Dobriskey, who won world 1500m silver in 2009.
"It was a nightmare at the time, I'd gone from seriously wanting an Olympic medal to being faced with not making the team.
"Thankfully, I got there and by the time the Olympics came around I was in a good place. I loved every second of the Games, but I have a pang of regret and sadness when I think back to it.
"I hoped for so much more but was just not good enough on the day. I feel I got as much as I could out of what I had to work with, but it wasn't what I wanted.
"Touch wood I am healthy. I've had a consistent block of training now and am making progress each day. It's been nice to run freely without the pressure of chasing times or team spots.
"I am really looking forward to racing as I haven't been able to race this time of year for a while due to injury, so I'm grateful to be healthy. I love running in Edinburgh as the supporters are amazing."
